本题详细解析:
Explanation:

The student must recognise that there are three proton environments in a $3:2:3$ ratio;
B has only $2$ environments ($3:2$ ratio), while C has $4$ ($3:2:2:1$). D has $3$ environments but they are in a $6:1:1$ ratio.
The question is hard as two pieces of information must be extracted from the spectrum and interpreted in the context of the structural formulas given.
