Task: Answer the multiple choice question.
Question: Which drug exhibits a -4.216\% 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 other words.
Options:
a O=C(NN1C(=O)C2C3C=CC(C3)C2C1=O)c1ccccc1
b COc1ccc(-c2cc(C(=O)NC3CCCC3)c3ccccc3n2)cc1
c CC1CCCC(NC(=O)COC(=O)[C@@H](NC(=O)c2ccco2)C(C)C)C1C
d CCN1CCN(C(=O)Cn2nc(-c3ccc(Cl)cc3)ccc2=O)CC1
Answer: c. CC1CCCC(NC(=O)COC(=O)[C@@H](NC(=O)c2ccco2)C(C)C)C1C
