Task: Answer the multiple-choice question.
Question: Which drug exhibits a -17.469% human ether-à-go-go related gene (hERG) inhibition at 10uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
(a) COc1ccccc1N(CCC#N)C(=O)COC(=O)c1cccn1C
(b) O=[N+]([O-])c1cc(/C=N/O)ccc1Oc1ccccc1Cl
(c) O=S(=O)(/C=C/c1ccccc1)N1CCN(c2ccccc2)CC1
(d) O=C(COC(=O)Cc1ccccc1)Nc1cc(S(=O)(=O)N2CCCCC2)ccc1Cl
Answer: a. COc1ccccc1N(CCC#N)C(=O)COC(=O)c1cccn1C
