Which of the following BEST defines static techniques?

The statement that best defines static techniques is D. Manual examination and automated analysis of code or project documentation. Static techniques are techniques that analyze the code or other software artifacts (such as requirements, specifications, designs, models, test cases, etc.) without executing them, and provide information about their quality, defects, complexity, maintainability, etc. Static techniques can be performed manually or automatically by using tools or methods such as reviews, inspections, walkthroughs, checklists, standards, guidelines, static analysis tools, code metrics tools, etc. Static techniques can help to improve the quality and consistency of code or other software artifacts throughout the software development life cycle and reduce the cost and effort of testing and debugging. A detailed explanation of static techniques can be found in [A Study Guide to the ISTQB® Foundation Level 2018 Syllabus], pages 27-34.
