Task: Answer the multiple choice question.
Question: Which compound exhibits a -4.962\% 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, d, or e without using any additional words.
Options:
a) COc1ccc(OC)c(CN2CCCC(C(=O)N3CCCCC3)C2)c1.O=C(O)C(=O)O
b) COCCn1c(Cc2ccccc2)nnc1SCc1ccc([N+](=O)[O-])cc1
c) Cl.Oc1ccccc1CNCC12CC3CC(CC(C3)C1)C2
d) COC(=O)CCNCCSc1nnc(-c2ccco2)n1Cc1ccccc1.O=C(O)C(=O)O
e) COC(=O)C1CCN(C(=O)COC(=O)COc2ccc(C#N)cc2)CC1
Answer: a. COc1ccc(OC)c(CN2CCCC(C(=O)N3CCCCC3)C2)c1.O=C(O)C(=O)O
