Task: Answer the multiple choice question.
Question: Which drug exhibits a 3.137\% 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. CC(=O)c1cc(-c2ccccc2)n(CC(=O)N2CCCC2)c1C
b. COc1ccc(CN(C)CC(=O)Nc2ccc(Cl)cc2C(F)(F)F)c(OC)c1.O=C(O)C(=O)O
c. COc1cc(CNC(=O)C2CCCC2)cc(OC)c1OC
d. c1ccc(CNc2ncnc3c2ncn3C2CCCCO2)cc1
e. O=C(Nc1cccc2ccccc12)c1cccc([N+](=O)[O-])c1
Answer: a. CC(=O)c1cc(-c2ccccc2)n(CC(=O)N2CCCC2)c1C
