Task: Answer the multiple choice question.
Question: Which drug exhibits a 21.169\% hERG inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a.) O=C(CN1C(=O)C(=O)N(Cc2ccco2)C1=O)NC1CCCCC1
b.) Fc1ccccc1N1CCN(c2cnc3ccccc3n2)CC1
c.) CCN1CCCC1CNC(=O)Cn1cccc1C(=O)c1ccccc1C
d.) O=C(NCc1cccnc1)c1cn(-c2ccccc2)nc1-c1cccs1
Answer: a. O=C(CN1C(=O)C(=O)N(Cc2ccco2)C1=O)NC1CCCCC1
