Strategy:
 Identify the block of an element by its valence shell electronic configuration. Use the atomic number to determine the filling of subshells.

Step 1: Analyze each atomic number
- (A) 37: . The last electron enters the -orbital. (s-block: IV)
- (B) 78: . The last electron belongs to the -orbital (Platinum). (d-block: II)
- (C) 52: . The last electron enters the -orbital (Tellurium). (p-block: I)
- (D) 65: . The last electron enters the -orbital (Terbium). (f-block: III)
