Task: Answer the multiple-choice question.
Query: Which drug exhibits a 4.930\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any other words.
Options:
(a) COc1ccc2oc(C(=O)N(Cc3ccco3)Cc3cccs3)c(C)c2c1
(b) Cc1ccc(NC(=O)N2N=C(c3ccc(F)cc3)CC2c2ccc(F)cc2)cc1
Answer: a. COc1ccc2oc(C(=O)N(Cc3ccco3)Cc3cccs3)c(C)c2c1
