Problem statement: Answer the multiple choice question.
Question: Which drug has a 0.393\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a: COCCn1c(=O)[nH]c2cc(C(=O)N3CCN(c4ccccc4OC)CC3)ccc2c1=O
b: O=C(Cn1cnc2c(NC(=O)OCc3ccccc3)ncnc21)NCc1ccccn1
Answer: b. O=C(Cn1cnc2c(NC(=O)OCc3ccccc3)ncnc21)NCc1ccccn1
