Task: Answer the multiple choice question.
Query: Which drug exhibits a 3.741\% 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(NCCOc1ccccc1Cl)C(=O)Nc1ccccc1
(b) COc1ccccc1-n1ccnc(SCC(=O)NC2CCCCC2)c1=O
(c) O=C(NC1CCCN(c2ccc(C(F)(F)F)cn2)C1)c1cc(Cl)ccc1F
Answer: a. O=C(NCCOc1ccccc1Cl)C(=O)Nc1ccccc1
