Comprehensive and Detailed Explanation From Exact Extract:

A string is a data type used to store sequences of characters, such as text or words. According to foundational programming principles (e.g., Certiport Scripting and Programming Foundations Study Guide), strings are ideal for textual data but not for numerical or boolean values, which have specific data types (e.g., integers, floats, booleans).

Option A: "A true/false indication of whether a number is composite." This is incorrect. A true/false value is a boolean, not a string. In most languages (e.g., Python’s True/False, C’s 0/1), booleans are a distinct type.

Option B: "A positive number between 2 and 3." This is incorrect. A number between 2 and 3 (e.g., 2.5) is a floating-point value, not a string. Strings could represent numbers as text (e.g., "2.5"), but this is not the primary use.

Option C: "The word 'positive'." This is correct. The word "positive" is a sequence of characters, perfectly suited for a string data type (e.g., char[] in C, str in Python).

Option D: "A positive whole number." This is incorrect. Whole numbers are stored as integers (e.g., int in C or Python), not strings, unless represented as text (e.g., "123"), which is not implied here.

 Dijkstra’s shortest path algorithm is designed to find the shortest path between nodes in a graph. This can be applied to various scenarios, such as routing problems, network optimization, and in this case, determining the most fuel-efficient flight plan. The algorithm works by iteratively selecting the unvisited vertex with the smallest tentative distance from the source, then visiting the neighbors of this vertex and updating their tentative distances if a shorter path is found. This process continues until the destination vertex is reached or all reachable vertices have been visited.

In the context of the given options, Dijkstra’s algorithm is best suited for option B, where the goal is to find the most fuel-efficient path (i.e., the shortest path) between multiple points (coordinates of five positions). The algorithm is not designed to solve problems like searching for an element in an array (option A), finding the longest common subsequence (option C), or searching for a name in a list (option D).

HTML (HyperText Markup Language) is a standard for structuring content on the web. According to foundational programming principles, HTML is a markup language, not a programming language, and does not involve typing (dynamic or static) or OOP.

Option A: "Dynamically typed." This is incorrect. HTML is not a programming language and does not involve variables or typing. Dynamic typing applies to languages like Python or JavaScript.

Option B: "Markup." This is correct. HTML is a markup language used to define the structure of web content using tags (e.g.,

,

).

Option C: "Statically typed." This is incorrect. HTML does not involve typing, as it is not a programming language. Static typing applies to languages like C or Java.

Option D: "Object-oriented." This is incorrect. HTML lacks OOP features like classes, inheritance, or polymorphism, as it is designed for content structuring, not programming.
