Task: Answer the multiple choice question.
Question: Which drug exhibits a 16.724\% 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) CCOc1ccccc1CNC(=O)c1cc2oc3ccccc3c2n1CC
(b) O=C(Nc1ccc2c(c1)OCO2)c1ccc([N+](=O)[O-])cc1[N+](=O)[O-]
(c) COc1ccc2nc(Cl)cc(Cl)c2c1
(d) Cc1ccc(C(NC(=O)CN2C(=O)NC3(CCCC3)C2=O)c2ccccc2)cc1
Answer: c. COc1ccc2nc(Cl)cc(Cl)c2c1
