Task: Answer the multiple choice question.
Query: Which compound exhibits a 2.951\% 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: Cc1nn(-c2ccccc2)c(Cl)c1/C=C(\CC(=O)O)c1nc2ccccc2s1
b: Cc1cc(NS(=O)(=O)c2ccc(NC(=S)NC(=O)c3cccc(S(=O)(=O)N(C)C)c3)cc2)no1
c: Cc1ccccc1Cn1cc(NC(=O)c2noc(C(C)C)c2[N+](=O)[O-])cn1
Answer: a. Cc1nn(-c2ccccc2)c(Cl)c1/C=C(\CC(=O)O)c1nc2ccccc2s1
