Task: Answer the multiple-choice question.
Question: Which drug exhibits a -1.273% hERG inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: O=C(CSc1nc(C2CC2)nc2ccccc12)Nc1ccccc1
b: CCNc1nc(NC(C)C)nc(Nn2cnnc2)n1
Answer: a. O=C(CSc1nc(C2CC2)nc2ccccc12)Nc1ccccc1
