Problem statement: Answer the multiple choice question.
Question: Which drug has a 12.806\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a or b without using any additional words.
Options:
a.) O=c1[nH]c2ccccc2nc1/C=C(\O)C1CC1
b.) CCCCN(C)C(=O)C1CCN(C/C(C)=C/c2ccccc2)CC1.O=C(O)C(=O)O
Answer: a. O=c1[nH]c2ccccc2nc1/C=C(\O)C1CC1
