Task: Answer the multiple choice question.
Query: Which drug exhibits a -16.280\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any additional words.
Options:
a: Cc1nn(-c2ccccc2)c(N)c1Sc1ccc([N+](=O)[O-])cc1
b: COc1ccc(NC(=O)C2CCOC(C)(C)C2)cc1
c: CCCCn1c(=O)c(C(=O)Nc2nnc(C(C)C)s2)c(O)c2ccccc21
Answer: a. Cc1nn(-c2ccccc2)c(N)c1Sc1ccc([N+](=O)[O-])cc1
