Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 15.000\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) Cc1[nH][nH]c(=O)c1C=Nc1ccc(C(F)(F)F)cc1
(b) COc1ccc(-c2cc(C(F)F)n3ncc(C(=O)N4CCN(C(=O)c5ccco5)CC4)c3n2)cc1
Answer: a. Cc1[nH][nH]c(=O)c1C=Nc1ccc(C(F)(F)F)cc1
