Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 2.800% 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(CCn1c(=O)[nH]c2ccccc2c1=O)N1CC=C(c2ccccc2)CC1
b. O=C(COC(=O)COc1ccccc1)NC1CCCC1
Answer: a. O=C(CCn1c(=O)[nH]c2ccccc2c1=O)N1CC=C(c2ccccc2)CC1
