Problem statement: Answer the multiple choice question.
Query: Which compound exhibits a -6.553\% human ether-à-go-go related gene (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: COCC(=O)Nc1ccccc1NC(C)=O
b: C=CCSc1nc(N)c(C(=O)Nc2ccccc2OC)cc1C(=O)Nc1ccccc1
c: Cc1ncc(C23CC4CC(CC(C4)C2)C3)[nH]1
d: Cc1cccc(Cn2cccc2/C=C2/C(=N)N3C=CSC3=NC2=O)c1
Answer: a. COCC(=O)Nc1ccccc1NC(C)=O
