Task: Answer the multiple-choice question.
Question: Which compound exhibits a -3.678% 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 or b without using any other words.
Options:
a.) O=C(Cc1cccs1)Nc1nc(-c2cccnc2)cs1
b.) CCCc1cc(=O)[nH]c(SCC(=O)Nc2ncc(S(=O)(=O)c3ccc([N+](=O)[O-])cc3)s2)n1
Answer: a. O=C(Cc1cccs1)Nc1nc(-c2cccnc2)cs1
