Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 10.107\% 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 additional words.
Options:
(a) COc1ccc([N+](=O)[O-])cc1NC(=O)Cc1ccccc1Cl
(b) CCOc1ccc(CN(C)CC(=O)Nc2cc(C)c(C)cc2[N+](=O)[O-])cc1.CN(C)C=O
(c) COC(=O)c1ccc(Cn2cc(Cl)cn2)o1
(d) COc1cccc(/C=N/NC(=O)C(=O)N/N=C/c2cccc(OC)c2OC)c1OC
Answer: a. COc1ccc([N+](=O)[O-])cc1NC(=O)Cc1ccccc1Cl
