Given the true statements: (1) If a is greater than b, then c is greater than d (2) If c is less than d, then e is greater than f. A valid conclusion is:
<spanclass=′latex−bold′>(A)</span>If a is less than b, then e is greater than f<spanclass=′latex−bold′>(B)</span>If e is greater than f, then a is less than b<spanclass=′latex−bold′>(C)</span>If e is less than f, then a is greater than b<spanclass=′latex−bold′>(D)</span>If a is greater than b, then e is less than f<spanclass=′latex−bold′>(E)</span>none of these
