Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 5.252% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) CCOc1ccccc1CNC(=O)CCNS(=O)(=O)c1ccc2[nH]c(=O)oc2c1
(b) CC1CCN(c2ccc(-c3ccc(NC(=O)c4ccco4)cc3)nn2)CC1
(c) O=C1NC(=Nc2ccccc2Cl)S/C1=C\c1cc([N+](=O)[O-])ccc1O
(d) COc1ccc(S(=O)(=O)N2CCCC(C(=O)NCc3ccccc3)C2)cc1
(e) CCNCc1ccc(OCc2cccs2)c(OCC)c1
Answer: c. O=C1NC(=Nc2ccccc2Cl)S/C1=C\c1cc([N+](=O)[O-])ccc1O
