Hot Potato

Logic

Andrew just cooked four potatoes ( $A, B, C$ , and $D$ ) in a microwave oven without a turntable. As a result of the unevenness of the radiation inside, the potatoes came out at different temperatures. Using just his hands, Andrew gathers the following empirical evidence:

$T_A>T_B$
$T_C<T_D$
$T_B=T_D$

Which potato is the hottest?

A B C D B and D A and C
