Task: Answer the multiple choice question.
Question: Which drug exhibits a 15.703\% 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(Cn1nc(C(F)F)cc1C1CC1)NCCC1=CCCCC1
(b) COc1ccc(N(C(=O)c2ccc(F)cc2)C2=CC3CCC(C2)N3C)cc1.Cl
(c) CCCCCn1c(SCc2cccc(C)c2)nc2c1c(=O)[nH]c(=O)n2C
(d) CN(C)/C=C1\C(=O)N(c2ccc(Oc3ccccc3)cc2)CS1=O
(e) CN(C)C1=NC[C@H](Cc2ccccc2)N1CC1CCCCC1
Answer: c. CCCCCn1c(SCc2cccc(C)c2)nc2c1c(=O)[nH]c(=O)n2C
