Problem statement: Answer the multiple-choice question.
Question: Which drug has a -5.977% 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, c, d, or e without using any additional words.
Options:
a: O=c1sc(Nc2ccccc2)nc2ccsc12
b: Cl.O=C(Nc1nc2n(n1)C(c1ccccc1)C=C(c1ccccc1)N2)c1ccco1
c: COC(=O)c1ccccc1NC(=S)NC(=O)C1CC1
d: O=c1c2ccccc2nc(-c2ccc([N+](=O)[O-])cc2)n1O
e: O=C(C1CC1)N1CCc2cc(Br)cc(S(=O)(=O)NC3CCCCC3)c21
Answer: a. O=c1sc(Nc2ccccc2)nc2ccsc12
