Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.661% 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, b, or c without using any additional words.
Options:
(a) Cc1ccn2cc(-c3cccc([N+](=O)[O-])c3)nc2c1
(b) COc1ccccc1CCNC(=O)c1nc(-c2cccs2)no1
(c) CN(C)c1ccc(C2N(C(=O)N3CCOCC3)CCN2S(=O)(=O)c2ccccc2)cc1
Answer: a. Cc1ccn2cc(-c3cccc([N+](=O)[O-])c3)nc2c1
