Step-by-Step Explanation:

Regression testing ensures that new changes do not break existing functionality. It would have identified the memory leak before deployment, preventing downtime.

Step-by-Step Explanation:

Understand the QuestionRequirements:The goal is to use a regular expression (regex) to match software versions 10.0 through 10.3, but exclude version 10.4.

Review Regex Syntax:

[ ] indicates a character set (matches any one character in the set).

[0-3] matches any digit between 0 and 3.

\. escapes the period (.) so it matches a literal period instead of acting as a wildcard.

( ) groups parts of the regex together.

Analyze Each Option:

Option A: Reader(*)[1][0] .[0-4:

Incorrect. The use of (*) is not valid syntax in this context and [0-4 is incomplete or misformatted.

Option B: Reader[11[01X.f0-3 '

Incorrect. This is an invalid regex syntax, mixing character sets and mismatched brackets.

Option C: Reader( )[1][0] .[0-3:

Correct. This regex is valid and matches " Reader 10.0 " , " Reader 10.1 " , " Reader 10.2 " , and " Reader 10.3 " while excluding " Reader 10.4 " .

Breakdown:

Reader: Matches the text " Reader " .

[1][0] : Matches " 10 " as a combination of two characters.

\.: Matches the literal period.

[0-3]: Matches any single digit between 0 and 3.

Option D: Reader( )[1][0] X.[1-3:

Incorrect. The syntax X.[1-3 is invalid, and this does not match the required versions.

Conclusion:The regex in Option C correctly identifies all affected versions (10.0, 10.1, 10.2, 10.3) while excluding the unaffected version (10.4).
