Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 0.608\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a COc1ccc(-c2nnc(SCc3ccc(C(=O)O)cc3)n2N)cc1
b CCOC(=O)C1=C(C)NC(=O)NC1c1cc(Br)c(O)c(OC)c1
c O=C(Nc1cccc(NC(=O)c2cc([N+](=O)[O-])ccc2Cl)n1)c1cc([N+](=O)[O-])ccc1Cl
d COc1ccc(NC(=O)CC2C(=O)N(c3ccc(F)cc3)C(=S)N2NC(=O)c2ccc(Cl)cc2)cc1
Answer: c. O=C(Nc1cccc(NC(=O)c2cc([N+](=O)[O-])ccc2Cl)n1)c1cc([N+](=O)[O-])ccc1Cl
