Task: Answer the multiple choice question.
Question: Which compound exhibits a -0.066\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: C=CCOC(=O)C1=C(C)N=C2SCCC(=O)N2C1c1ccc(OC(=O)c2ccco2)cc1
b: Cc1[nH]ccc2c1[nH]c1cc(=O)ccc12
c: COc1ccc2ccccc2c1/C=N/O
d: CCOC(=O)C(C(C)=O)C(c1ccc(OC)cc1)C(C(C)=O)C(=O)OCC
Answer: d. CCOC(=O)C(C(C)=O)C(c1ccc(OC)cc1)C(C(C)=O)C(=O)OCC
