Task: Answer the multiple choice question.
Question: Which drug exhibits a 10.976\% 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.) CCN(CC)C(=O)Nc1ccccc1C
b.) CCCC(C)C(=O)NCc1ccccc1OC
c.) CCOC(=O)C1CCN(C(C)=C2C(=O)c3ccccc3C2=O)CC1
d.) CCOC(=O)CSC1=C(C#N)C(=O)NC2(CCCCC2)S1
Answer: a. CCN(CC)C(=O)Nc1ccccc1C
