Problem statement: Answer the multiple choice question.
Query: Which compound has a 0.521\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a.) CN1CCC(=O)N([C@H](CSc2ccccc2)c2ccccc2)CC1
b.) O=C(c1cn(-c2ccccc2)nc1-c1cccs1)N1CCN(c2ccccc2)CC1
c.) O=C(NNc1ccccc1[N+](=O)[O-])Nc1ccc(F)cc1
Answer: c. O=C(NNc1ccccc1[N+](=O)[O-])Nc1ccc(F)cc1
