Which type of security testing is MOST efficient for finding hidden errors in software and...

White box testingis the most effective foridentifying hidden errorsand optimizingsource code quality.

Option A (Incorrect):UAT focuses on functionalityfrom anend-user perspective, not source code errors.

Option B (Incorrect):Black box testingexamines software behaviorwithout reviewing code, making it less effective for code-level optimization.

Option C (Correct):White box testing(also known asclear box or structural testing)analyzes source codefor vulnerabilities, logic errors, and optimization opportunities.

Option D (Incorrect):Penetration testingidentifiessecurity weaknesses, but it does notfocus on code efficiency.
