Task: Answer the multiple choice question.
Query: Which drug exhibits a 4.429\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any additional words.
Options:
(a) O=C(NC1CCCCCCC1)c1cc(F)c(F)cc1Cl
(b) Cc1ccc(NC(=O)CSc2nc3c(c(=O)[nH]2)CN(Cc2ccc(F)cc2)CC3)cc1C
(c) CCOC(=O)c1sc(NC(=O)CSc2n[nH]c(-c3ccncc3)n2)c(C#N)c1C
(d) COc1ccccc1/C=C(\NC(=O)c1ccccc1)C(=O)NCc1ccco1
(e) CC1CCN(C(=O)COc2ncnc3ccccc23)CC1
Answer: a. O=C(NC1CCCCCCC1)c1cc(F)c(F)cc1Cl
