Problem statement: Answer the MCQ question.
Query: Which drug exhibits a -22.080\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
(a) Cc1cc2c(c(=O)o1)C(c1cccs1)C(C#N)=C(N)O2
(b) CCOc1[nH]n(-c2ccccc2)c(=O)c1C=Nc1ccc(C)cc1
Answer: b. CCOc1[nH]n(-c2ccccc2)c(=O)c1C=Nc1ccc(C)cc1
