Task: Answer the multiple-choice question.
Query: Which compound exhibits a 8.925\% 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 additional words.
Options:
a: O=C(CN(C(=O)CCC(=O)Nc1nccs1)c1ccc(F)c(Cl)c1)NCC1CCCO1
b: CCCCn1c(N)c(N(CCC(C)C)C(=O)C2CCCC2)c(=O)[nH]c1=O
c: O=c1c2c(nc3c(-c4ccccc4)c[nH]n13)CCCC2
d: COC(=O)c1ccc(C2C(C#N)=C(N)Oc3cc(C)n(C)c(=O)c32)cc1
Answer: d. COC(=O)c1ccc(C2C(C#N)=C(N)Oc3cc(C)n(C)c(=O)c32)cc1
