Problem statement: Answer the multiple-choice question.
Question: Which compound has a 2.847\% 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, or d without using any other words.
Options:
a CCCCOC(=O)Nc1cc(C)c(Cl)cc1OC
b O=C(CN(C(=O)CCC(=O)Nc1nccs1)c1ccc(F)c(Cl)c1)NCc1ccco1
c COC1=CC(=O)OC12CCCCC2
d C=CCn1c(-c2ccc([N+](=O)[O-])cc2)n[nH]c1=S
Answer: a. CCCCOC(=O)Nc1cc(C)c(Cl)cc1OC
