Task: Answer the multiple-choice question.
Question: Which drug has a 8.584\% 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.) CCn1nnc(NC(=O)c2ccc([N+](=O)[O-])o2)n1
b.) COc1ccc(-c2cc3ccccc3c(=O)n2CCc2cccs2)cc1
c.) COc1ccccc1S(=O)(=O)Cc1ccc(C(=O)NCc2ccc(C)cc2)o1
d.) O=C(NCC(c1ccco1)N1CCCC1)c1cccc(NS(=O)(=O)c2ccccc2)c1
Answer: a. CCn1nnc(NC(=O)c2ccc([N+](=O)[O-])o2)n1
