Task: Answer the MCQ question.
Query: Which compound has a -55.361% human ether-à-go-go related gene (hERG) inhibition at a concentration of 10uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
a O=C(CN1CCCc2ccccc21)Nc1ccccc1[N+](=O)[O-]
b CN1CCN(C(=O)Nc2ccccc2)CC1.O=C(O)C(=O)O
c CCCCCCN=C(CC)c1c(O)n(CCCC)c(=O)[nH]c1=O
Answer: c. CCCCCCN=C(CC)c1c(O)n(CCCC)c(=O)[nH]c1=O
