Task: Answer the multiple-choice question.
Query: Which drug exhibits a -31.217% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a O=C(NCc1cccs1)c1ccc([N+](=O)[O-])cc1
b CCC(Oc1ccccc1OC)C(=O)Nc1ccc2c(c1)OCO2
c CCN1C(=O)/C(=C\c2ccc(F)cc2)N=C1SCC(=O)NCc1ccco1
d O=C(NC1CCS(=O)(=O)C1)Oc1ccccc1
Answer: a. O=C(NCc1cccs1)c1ccc([N+](=O)[O-])cc1
