Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 3.760\% human ether-à-go-go related gene (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) O=C(Nc1cccc(Br)c1)c1ccc(CSc2ccccc2)cc1
(b) COc1ccc2nc3cc(Cl)ccc3c(C#N)c2c1
Answer: a. O=C(Nc1cccc(Br)c1)c1ccc(CSc2ccccc2)cc1
