Task: Answer the multiple-choice question.
Query: Which drug exhibits a 3.850\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a) COc1ccc(C(=O)c2oc3nc(C)cc(C)c3c2N)cc1
b) C=C(NC(C)=O)c1c(F)cccc1F
c) O=C(COc1ccc([N+](=O)[O-])cc1)Nn1cnnc1
d) COC(=O)c1ccc(NC(=O)C2CCN(S(C)(=O)=O)CC2)cc1
Answer: a. COc1ccc(C(=O)c2oc3nc(C)cc(C)c3c2N)cc1
