Task: Answer the multiple-choice question.
Question: Which drug exhibits a 5.199\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) CSc1nc(-c2ccc(Cl)cc2Cl)[nH]c(=O)c1C#N
(b) CCOC(=O)c1cc(C(=O)NC(C)c2ccccc2)c(=O)[nH]c1C
(c) CCOC(=O)c1c(C)[nH]c(C(=O)OC(C)C(=O)Nc2ccc(Cl)cn2)c1C
Answer: a. CSc1nc(-c2ccc(Cl)cc2Cl)[nH]c(=O)c1C#N
