Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.451\% human ether-à-go-go related gene (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 additional words.
Options:
a: COc1cccc(CC(NC(C)=O)C(=O)NC2CCN(S(=O)(=O)c3ccc4ccccc4c3)CC2)c1
b: COc1ccccc1NC(=O)C1CCN(c2ncnc3c2nc2n3CCCCC2)CC1
c: N#CC(C#N)=C(N)Nc1cccc(Cl)c1
d: COc1ccc(NC(C)=O)cc1C
Answer: a. COc1cccc(CC(NC(C)=O)C(=O)NC2CCN(S(=O)(=O)c3ccc4ccccc4c3)CC2)c1
