Task: Answer the multiple-choice question.
Query: Which drug has a 18.275\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
a.) COc1ccc(NC(=O)c2cc(-c3ccncc3)nc3ccc(Br)cc23)cc1OC
b.) COc1ccc(C2CC(c3cccs3)=NN2C(=O)CCC(=O)O)cc1
c.) COc1ccc(NC(=O)Cn2c(=O)c(C)nc3ccccc32)cc1Cl
d.) CCCCNc1c(N)n(CCC)c(=O)[nH]c1=O
Answer: d. CCCCNc1c(N)n(CCC)c(=O)[nH]c1=O
