   A test team has achieved 100% branch coverage on a module. The project manager asks whether this guarantees that all executable statements have been executed. What is the correct response?

   • AYes, 100% branch coverage implies 100% statement coverage
   • BYes, but only if the module has no loops
   • CNo, because branch coverage only measures decisions, not statements
   • DNo, 100% branch coverage does not guarantee 100% statement coverage
