Task: Answer the multiple-choice question.
Question: Which drug exhibits a 14.206\% 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. COc1ccc(C(=O)CSc2nnc3ccc(-c4ccccn4)nn23)cc1
b. O=C(C1Cc2ccccc2CN1S(=O)(=O)c1ccc(F)cc1)N1CCCCCC1
c. O=C(O)c1ccc([N+](=O)[O-])c(CS(=O)(=O)c2ccccc2)c1
Answer: a. COc1ccc(C(=O)CSc2nnc3ccc(-c4ccccn4)nn23)cc1
