Task: Answer the multiple-choice question.
Query: Which drug exhibits a 2.420\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
(a) O=C(NCCNS(=O)(=O)c1ccccc1Cl)c1cc(OCC(F)(F)F)ccc1OCC(F)(F)F
(b) COCCCNc1nc2c(c(=O)[nH]c(=O)n2C)n1CCCc1ccccc1
(c) CC(C)(C)NC(=O)NC(=O)CN1CCN(S(=O)(=O)c2ccccc2)CC1
Answer: a. O=C(NCCNS(=O)(=O)c1ccccc1Cl)c1cc(OCC(F)(F)F)ccc1OCC(F)(F)F
