Task: Answer the multiple choice question.
Question: Which compound has a 9.874\% 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(NCCN=C1NS(=O)(=O)c2ccccc21)c1ccccc1
b COc1cccc(-c2ccc(C#N)c(=O)[nH]2)c1
c C=CCn1c(-c2ccccc2)n[nH]c1=S
d COc1ccc(NC(=O)CCS(=O)(=O)c2cc3c(cc2C)NC(=O)CO3)cc1
Answer: b. COc1cccc(-c2ccc(C#N)c(=O)[nH]2)c1
