Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a 0.387\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
(a) CCC1(CC)C(=O)N=C2c3ccccc3C(=O)N21
(b) Cc1ccc(-c2nnc(Nc3ccccc3)o2)cc1
(c) CC(=O)N1CCC(C(=O)Nc2ccccc2)(N(Cc2ccccc2)C(=O)c2cccnc2)CC1
(d) O=S(=O)(Cc1cc(NCc2ccccc2)nc(-c2ccccn2)n1)c1ccccc1
(e) CCOC(=O)/C(C#N)=C1\C=CN(C)C(C)=N1
Answer: a. CCC1(CC)C(=O)N=C2c3ccccc3C(=O)N21
