   A test team has two weeks to test a new adaptive cruise control (ACC) system and a legacy radio. The ACC is safety-critical, but the radio has a contractual deadline. How should the team prioritize testing?

   • ATest the radio first because it has more features.
   • BTest the ACC first and allocate most of the time to it; test the radio with the remaining time.
   • CSplit the two weeks equally between the two systems.
   • DTest the radio first to meet the contractual deadline, then test the ACC if time remains.
