Which of the following statements about loop testing is false?

a. It supplements basis path testing because loops will not be traversed with test data designed using basis path testing

b. With nested loops, testing should commence with the innermost loop and work outwards to the outermost loop

c. With simple loops, the loop should be checked at its lower boundary by exercising zero, one, and two passes through the loop

d. Providing concatenated loops are independent of one another, they can be tested using the strategies developed for simple loops and nested loops
