Task: Answer the multiple-choice question.
Question: Which drug exhibits a -4.066\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a CCOP(=O)(OCC)/C(C#N)=C/c1ccc([N+](=O)[O-])cc1
b O=C(CCc1nc2ccccc2s1)OCc1ccccc1F
c O=C(c1ccco1)N1CCN(C2=NS(=O)(=O)c3ccccc32)CC1
d CC(C)OC(=O)C(CC(=O)O)NCc1ccccc1
e CCOC(=O)CSc1ccc2ccccc2n1
Answer: a. CCOP(=O)(OCC)/C(C#N)=C/c1ccc([N+](=O)[O-])cc1
