Task: Answer the multiple choice question.
Question: Which drug exhibits a 6.416\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: CCc1cc(=O)[nH]c(SCC(=O)N2CCCC2)n1
b: CCOC(=O)c1sc(=S)n(C)c1NC(=O)c1ccc(OC)cc1
c: O=C(c1cccc(-c2ccccc2)c1)N1CC[C@@H](N2CCC(O)CC2)[C@H](O)C1
Answer: a. CCc1cc(=O)[nH]c(SCC(=O)N2CCCC2)n1
