   What is a primary limitation of MC/DC?

   • AIt is only applicable to decisions with a single condition
   • BIt provides no more assurance than branch coverage
   • CIt does not require executing all statements

   A safety-critical system has a decision with 10 conditions. The team is considering whether to require MC/DC coverage. Which of the following is the primary trade-off they should consider?

   • AMC/DC is only applicable to decisions with two conditions.
   • BMC/DC guarantees the absence of all software defects in the decision logic.
   • CMC/DC is always the cheapest coverage criterion to satisfy.
   • DMC/DC requires significantly more test cases than branch coverage, increasing test effort and cost.

   What is the primary purpose of Modified Condition/Decision Testing (MC/DC) in software testing?

   • ATo execute every possible combination of conditions in a decision
   • BTo ensure that every branch in the code is taken at least once
   • CTo verify that each condition in a decision can independently affect the decision's outcome
   • DTo ensure every statement in the code is executed at least once

   How does MC/DC compare to condition coverage?

   • AMC/DC is equivalent to condition coverage
   • BMC/DC is weaker than condition coverage
   • CMC/DC is stronger than condition coverage because it requires each condition to independently affect the decision's outcome
   • DMC/DC is only applicable to decisions with a single condition
