A.a construct that repeatedly runs its body for as long as a guarding command keeps returning a successful exit status
B.a construct that repeats its body until a guarding command first succeeds, the logical inverse of the success-driven repeating loop
C.an iteration construct that walks through a list of words one at a time, binding each to a loop variable for the body
D.a line-by-line iteration pattern that pipes or redirects input into a builtin which assigns each line to variables for processing
