Task: Answer the multiple choice question.
Question: Which compound exhibits a 8.953\% 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 CCCCn1c(O)c(C(C)=NCCc2ccccc2)c(=O)[nH]c1=O
b Cc1ccc(NS(=O)(=O)c2cccc3nsnc23)cc1[N+](=O)[O-]
c CCCCC(=O)N/N=C/c1c(O)n(CC)c(=S)[nH]c1=O
Answer: c. CCCCC(=O)N/N=C/c1c(O)n(CC)c(=S)[nH]c1=O
