Solution

The correct answer is 2) B, C Only.

Key Points

• Software Quality Assurance (SQA) involves ensuring that software processes and products adhere to defined standards and procedures.
• It is a preventive technique (Option C) because it focuses on preventing defects in the software development process rather than detecting defects after they occur.
• SQA activities typically involve no execution of code (Option B) but focus on process implementation, audits, and reviews.

Additional Information

• Option A: Execution of code - This is typically associated with software testing, which is a part of quality control, not quality assurance.
• Option D: A corrective technique - This refers to addressing defects after they have been identified, which is more aligned with quality control rather than quality assurance.
