Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 8.101\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
(a) COc1cccc(CC(=O)N2CCN(c3ccccc3[N+](=O)[O-])CC2)c1
(b) CCOC(=O)N1CCN(c2ccc([N+](=O)[O-])cc2)CC1
(c) Cc1nn(-c2cccc([N+](=O)[O-])c2)c(N)c1-c1ccccc1
(d) O=C(NCCN1CCCCCC1)C1CCN(S(=O)(=O)N2CCOCC2)CC1
Answer: a. COc1cccc(CC(=O)N2CCN(c3ccccc3[N+](=O)[O-])CC2)c1
