Task: Answer the multiple-choice question.
Question: Which drug exhibits a -4.800\% 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) O=C(CSc1nnc2n(C3CCCC3)c(=O)c3ccccc3n12)N1CCCCCC1
(b) Fc1ccc(NCc2cccnc2)cc1F
(c) O=C(CCNS(=O)(=O)c1ccc(Cl)cc1)OCC(=O)c1ccc[nH]1
Answer: a. O=C(CSc1nnc2n(C3CCCC3)c(=O)c3ccccc3n12)N1CCCCCC1
