Task: Answer the multiple choice question.
Query: Which drug exhibits a 2.979\% 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] Cc1nn(-c2cc(C(F)(F)F)ccc2Cl)c2nc(C(F)(F)F)[nH]c(=O)c12
[b] COc1ccc(OC)c(NC(=O)CSc2sc3c(O)cc(=O)[nH]c3c2C#N)c1
Answer: b. COc1ccc(OC)c(NC(=O)CSc2sc3c(O)cc(=O)[nH]c3c2C#N)c1
