Problem statement: Answer the multiple choice question.
Question: Which compound exhibits a 0.255\% 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 additional words.
Options:
a: CCCn1cc(SCC(=O)NC2CCCC2)c2ccccc21
b: O=C(NC1CCCC1)C(c1ccccn1)N(Cc1ccccc1F)C(=O)c1csnn1
c: O=C(Nc1ccc2nc3n(c(=O)c2c1)CCCC3)c1cc([N+](=O)[O-])ccc1F
Answer: c. O=C(Nc1ccc2nc3n(c(=O)c2c1)CCCC3)c1cc([N+](=O)[O-])ccc1F
