Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The requirement 'The response time shall be less than one second' is testable because it specifies a measurable performance criterion. Requirements like 'user friendly' and 'portable' are subjective and untestable. The requirement '0 faults' is unrealistic and untestable since zero defects cannot be guaranteed or verified.
