• A. 100% or 6/6
• B. 50% or 3/6
• C. 67% or 4/6
• D. 83% or 5/6

Answer: D

Explanation:
Test case 1 exercises the decision outcomes True, False, False
Test case 2 exercises the decision outcomes False, True, False This leaves the True outcome of decision 3 not exercised. Of the 6 possible decision outcomes, 5 have been exercised, so the decision coverage is 5/6 (about 83%).
