2. Proposition 1: The surface of a cube can be divided into 2, 3, or 4 completely congruent shapes. Proposition 2: In space, there is one and only one point that has the minimum sum of distances to the 8 vertices of the cube. Among the two propositions ( ).
A. Neither is correct
B. The first is incorrect, the second is correct
C. The first is correct, the second is incorrect
D. Both are correct
2. D

Question 1. The division is as shown in the figure.
Proposition 2. Let the cube be $A B C D-A^{\prime} B^{\prime} C^{\prime} D^{\prime}, O$ be its center, and $P$ be any point in space, then $P A+P C^{\prime} \geqslant A C^{\prime}, P B+P D^{\prime} \geqslant B D^{\prime}, P C+P A^{\prime} \geqslant C A^{\prime}, P D+P B^{\prime} \geqslant D B^{\prime}$.

Therefore, $P A+P B+P C+P D+P A^{\prime}+P B^{\prime}+P C^{\prime}+P D^{\prime} \geqslant A C^{\prime}+B D^{\prime}+$ $C A^{\prime}+D B^{\prime}$, equality holds if and only if $P=O$.
