Task: Answer the multiple-choice question.
Query: Which compound exhibits a 20.255\% 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 CCCC(=O)c1c[nH]c(C(=O)NCCc2ccccn2)c1
b CC1(C)Cc2c(sc3nnn(Cc4ccccc4)c(=O)c23)CO1
c CC(=O)Nc1ccccc1C(=O)C(=O)Nc1ccc(C(=O)NCC2CCCO2)cc1
d COc1cc(C(c2c(C)[nH]n(-c3ccccc3)c2=O)c2c(C)[nH]n(-c3ccccc3)c2=O)cc(OC)c1OC
Answer: d. COc1cc(C(c2c(C)[nH]n(-c3ccccc3)c2=O)c2c(C)[nH]n(-c3ccccc3)c2=O)cc(OC)c1OC
