Task: Answer the multiple choice question.
Question: Which compound exhibits a 13.622\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, d, or e without using any other words.
Options:
a COc1ccc(-c2c(C#N)c(N)nc3c2CCCC3)cc1OC
b CC(=O)CC(=O)Nc1ccc2ccccc2c1
c O=C(Nc1ccccc1)Nc1cccc(Cl)c1
d CN(C)c1nccc(N(Cc2ccccc2)Cc2ccccc2)c1C#N
e Cc1ccc2nc(CCc3nc4ccc(C)cc4o3)oc2c1
Answer: a. COc1ccc(-c2c(C#N)c(N)nc3c2CCCC3)cc1OC
