Task: Answer the multiple-choice question.
Query: Which drug exhibits a -2.122\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) O=C(CSc1ccc(-c2ccccc2)nn1)N1CCCc2ccccc21
b.) CC(=O)NCCC(=O)Nc1ncc(S(=O)(=O)c2ccc([N+](=O)[O-])cc2)s1
c.) CC(C)NC(=S)NC(=O)c1ccc(-c2ccccc2)cc1
d.) CN1C(=O)/C(=C/c2ccc(OCc3ccc(C(=O)O)cc3)c(Cl)c2)NC1=S
Answer: a. O=C(CSc1ccc(-c2ccccc2)nn1)N1CCCc2ccccc21
