Task: Answer the multiple-choice question.
Query: Which drug exhibits a 5.913\% 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. CN=c1scc(-c2ccc([N+](=O)[O-])cc2)n1/N=C/c1ccco1
b. NC(=O)c1ccsc1NC(=O)c1ccc(S(=O)(=O)N2CCCC2)cc1
c. CC(=O)Nc1ccc2c(c1)nc1n2CCN(C(C)c2ccccc2)C1
Answer: a. CN=c1scc(-c2ccc([N+](=O)[O-])cc2)n1/N=C/c1ccco1
