Problem statement: Answer the multiple-choice question.
Question: Which compound exhibits a 9.944\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] COc1ccc(NS(=O)(=O)c2c(C)n(C)c(=O)n(C)c2=O)cc1OC
[b] O=C(CCl)NNC(=O)c1c(O)c2ccccc2[nH]c1=O
[c] O=C(NCCO)c1c(O)c2cccc3c2n(c1=O)CC3
Answer: b. O=C(CCl)NNC(=O)c1c(O)c2ccccc2[nH]c1=O
