Problem statement: Answer the multiple-choice question.
Query: Which drug exhibits a -12.009% 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 other words.
Options:
a) O=C(NCCNS(=O)(=O)c1ccccc1)c1ccc([N+](=O)[O-])cc1
b) O=C1O/C(=C\c2ccccc2)c2ccccc21
c) CC1CN(C(=O)CCC(=O)N2CCCCC2)c2ccccc2O1
d) O=C(Cn1nc(-c2ccccc2)ccc1=O)NCc1ccc2c(c1)OCO2
Answer: a. O=C(NCCNS(=O)(=O)c1ccccc1)c1ccc([N+](=O)[O-])cc1
