Problem statement: Answer the multiple choice question.
Question: Which drug exhibits a 13.597\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) NC(=O)CN1C(=O)NC2(CCCc3ccccc32)C1=O
b.) O=C(CN1CCC(NC(=O)c2ccco2)CC1)Nc1cccc2ccccc12
c.) CCOc1ccccc1CNC(=O)c1cc2oc3ccccc3c2n1C
d.) C[C@H](NC(N)=O)C(=O)OCC(=O)Nc1ccc(OC(F)F)cc1
Answer: a. NC(=O)CN1C(=O)NC2(CCCc3ccccc32)C1=O
