You test a system that grants a driving license. You design test cases based on the following minimized decision table.

You have already designed three following test cases:

• 18 years old, passed both vision and driving tests; expected result: grant a license
• 17 years old, passed vision test, failed driving test; expected result: do not grant a license
• 19 years old, failed both vision and driving tests; expected result: do not grant a license

Which test case needs to be added to this set to achieve full decision table coverage?

C. 18 years old, passed vision test, failed driving test; expected result: do not grant a license
