Task: Answer the multiple choice question.
Question: Which drug exhibits a -18.366% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] COc1ccc(C(=O)NCC2(c3ccccc3)CCOCC2)cc1[N+](=O)[O-]
[b] CS(=O)(=O)N(CC(=O)Nc1ccc(F)c(F)c1)c1cccc([N+](=O)[O-])c1
[c] CCC(=O)N(CCC(c1ccc(C)cc1)c1ccco1)Cc1ccco1
Answer: a. COc1ccc(C(=O)NCC2(c3ccccc3)CCOCC2)cc1[N+](=O)[O-]
