Problem statement: Answer the multiple choice question.
Query: Which drug has a 9.933% 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) COc1ccccc1C(C)NC(=O)c1cc(=O)[nH]c2ccccc12
(b) O=C(C1COc2ccccc2O1)N1CCN(c2ccccn2)CC1
(c) O=c1cc(-c2ccccc2Cl)oc2ccc([N+](=O)[O-])c(O)c12
Answer: c. O=c1cc(-c2ccccc2Cl)oc2ccc([N+](=O)[O-])c(O)c12
