Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 6.045\% 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(OC)c(Nc2ccc(C(=O)O)cc2[N+](=O)[O-])c1
b: CC1(C)CC(=O)C=C(Nc2ccc(F)c(Cl)c2)C1
c: CCOc1ncccc1C(=O)N(C)CC(=O)Nc1ccccc1SC
d: CCOc1ccccc1N1CCN(C(=O)c2cc3c(s2)CCC3)CC1
Answer: a. COc1ccc(OC)c(Nc2ccc(C(=O)O)cc2[N+](=O)[O-])c1
