Task: Answer the multiple choice question.
Query: Which drug exhibits a -4.608\% 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 Cc1ccc(-c2cc(=O)[nH][nH]2)c(C)c1
b COc1ccc(OC)c(S(=O)(=O)Nc2ccc3oc4c(c3c2)C(=O)CCC4)c1
Answer: a. Cc1ccc(-c2cc(=O)[nH][nH]2)c(C)c1
