Answer: C

Explanation:

To be based on an analysis of the structure of the component or system. White box testing techniques are based on the internal structure and code of the system, not on its specifications or functionality. White box testing techniques include statement coverage, decision coverage, branch coverage, path coverage, etc. White box testing techniques are usually performed at lower levels of testing, such as unit testing or component testing. A detailed explanation of white box testing techniques can be found in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], pages 68-74.
