Problem statement: Answer the multiple choice question.
Question: Which compound has a 13.578\% 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 CCCCCc1c(C)nc(Nc2ccccc2)[nH]c1=O
b Cc1ccc(N(C(=O)Cn2nnc(-c3ccccc3F)n2)C(C(=O)NC2CCCC2)c2ccncc2)cc1
c CCOC(=O)c1c(NC(=O)C2COc3ccccc3O2)sc2c1CC(C)(C)NC2(C)C
d CCOC(=O)c1c(SC)nc(SC)c2c1CCC2
Answer: a. CCCCCc1c(C)nc(Nc2ccccc2)[nH]c1=O
