Task: Answer the multiple-choice question.
Question: Which drug exhibits a -14.046% 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, d, or e without using any other words.
Options:
(a) CCCCNC(=O)COc1ccccc1[N+](=O)[O-]
(b) O=S(=O)(Nc1ncnc2c1oc1ccccc12)c1ccc(Cl)s1
(c) CC(C)(C)C(=O)Nc1ccc(-c2cn3cccnc3n2)cc1
(d) COc1ccc(C=O)c(OC)c1
(e) C/C(Nc1ccc(C)cc1)=C(/C#N)C(N)=O
Answer: a. CCCCNC(=O)COc1ccccc1[N+](=O)[O-]
