Let A and B be subsets of a universe U On each line put a checkmark if and only if the statement is true OA If U is infinite and Ac is finite then A is infinite OB If A is infinite and U is infinite then A is finite OC If A is infinite and B is finite then AUB is infinite OD If A is finite and B is finite then AUB is finite E If A is infinite then A B is infinite E If A is infinite and B is infinite then An B is infinite
