Task: Answer the multiple choice question.
Question: Which drug exhibits a -34.574\% 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. COc1ccc(OS(N)(=O)=O)c(CC(C)C)c1
b. c1ccc(CSc2nnc(-c3ccco3)o2)cc1
c. CN1CCN(C(c2cccc(Cl)c2)c2ccccc2Cl)CC1.O=C(O)/C=C\C(=O)O
d. Cc1ccc(Cl)cc1NC(=O)COc1ccccc1
e. CCOC(=O)C(=O)Nc1ccc(OCc2ccccc2)cc1
Answer: c. CN1CCN(C(c2cccc(Cl)c2)c2ccccc2Cl)CC1.O=C(O)/C=C\C(=O)O
