Problem statement: Answer the multiple choice question.
Query: Which drug exhibits a 12.615\% 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. CN1C(=O)C(c2ccccc2)C(=O)N(C)C1=O
b. C=CCn1c(=NC(=O)C2CC2)sc2cc(NC(C)=O)ccc21
Answer: a. CN1C(=O)C(c2ccccc2)C(=O)N(C)C1=O
