100% branch coverage means 100% statement coverage, but not vice-versa. Branch coverage is a stronger criterion than statement coverage, as it requires that every possible outcome of each decision point is executed at least once. Statement coverage only requires that every executable statement is executed at least once1 explains this as follows:

Branch Coverage (also known as Decision Coverage) measures which possible branches in flow control structures are followed. Branch Coverage is a testing method, which aims to ensure that each one of the possible branch from each decision point is executed at least once and thereby ensuring that all reachable code is executed.

Statement Coverage measures the number of statements in the source code that are executed during the test. Statement Coverage is a metric, which is used to calculate and measure the number of statements in the source code which have been executed during testing.

B, C, and D are false statements. 100% statement coverage does not mean 100% branch coverage (B), as there may be some branches that are not covered by the test cases. 100% branch coverage does not mean 100% statement coverage and vice-versa ©, as branch coverage implies statement coverage but not the other way around. It is possible to achieve 100% statement coverage (D), but it may not be feasible or cost-effective for some systems.

 Having the company’s independent test team design and execute the tests would achieve the highest level of testing independence for a project’s test level, because it would reduce the bias and influence of the developers or other stakeholders who are involved in the software development1 . An independent test team can provide a different perspective and focus on testing activities without being affected by development pressures or deadlines1 . The other options would not achieve the highest level of testing independence for a project’s test level. Option A is not a good option, because training developers to design good tests for the test team to execute would still introduce some bias and influence from the developers’ point of view1 . Option C is not a good option, because minimizing contact between testers and developers during test design to avoid bias would reduce the communication and collaboration that are essential for effective testing and defect resolution1 . Option D is not a good option, because outsourcing test design and execution to a different company would introduce some risks and challenges such as contractual issues, cultural differences, or loss of control over quality

Static code analysis is a technique that examines the source code or other software artifacts without executing them, and can detect defects, vulnerabilities, code smells, and deviations from standards early in the development process1. According to the ISTQB syllabus, one of the benefits of static testing is early defect detection2, which can reduce the cost and effort of fixing them later.
