Task: Answer the multiple choice question.
Question: Which drug exhibits a -25.738% 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, c, or d without using any other words.
Options:
(a) COc1ccc2[nH]cc(CCNC(=O)C3CC(=O)N(c4ccc(Cl)cc4)C3)c2c1
(b) CC(C)CC1(C)NC(=O)N(Cc2cc([N+](=O)[O-])cc3c2OCOC3)C1=O
(c) O=C(c1ccc(COc2ccccc2[N+](=O)[O-])o1)N1CCCCC1
(d) CCN(c1ccccc1)S(=O)(=O)c1cc([N+](=O)[O-])ccc1N
Answer: c. O=C(c1ccc(COc2ccccc2[N+](=O)[O-])o1)N1CCCCC1
