Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a -66.345% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a: O=C(NCCCN1CCN(c2ccccc2F)CC1)Nc1ccc(F)cc1
b: CCN(CC)S(=O)(=O)c1ccc(N2CCCC2)c(NS(=O)(=O)c2cccs2)c1
c: CCC1CCCCN1C(=O)COC(=O)CSc1ccc(C(N)=O)cc1[N+](=O)[O-]
Answer: a. O=C(NCCCN1CCN(c2ccccc2F)CC1)Nc1ccc(F)cc1
