Problem statement: Answer the multiple-choice question.
Query: Which drug has a -7.486\% 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, c, or d without using any other words.
Options:
(a) Cc1cc(NC(=O)c2cc(-c3ccc(C)c(C)c3)nc3ccccc23)no1
(b) O=C1SCC(c2ccc(Cl)cc2Cl)=NN1Cc1nnc(-c2ccccc2)o1
(c) CCOC(=O)N1CCN(C(=O)COc2ccc([N+](=O)[O-])cc2)CC1
(d) COc1cccc([C@@H]2CC=C(C(=O)O)[C@H](c3ccc(F)cc3)N2S(=O)(=O)c2ccc(C)cc2)c1
Answer: c. CCOC(=O)N1CCN(C(=O)COc2ccc([N+](=O)[O-])cc2)CC1
