Task: Answer the MCQ question.
Question: Which compound exhibits a 3.951\% 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) O=C(Nc1nc2ccccc2[nH]1)Nc1ccccc1F
(b) CCC1C(=O)N=C(SCC(=O)Nc2ccc(C)cc2)N(c2ccccc2)C1=O
(c) O=C(c1ccc(Cl)c([N+](=O)[O-])c1)N(Cc1ccco1)C1CCS(=O)(=O)C1
Answer: c. O=C(c1ccc(Cl)c([N+](=O)[O-])c1)N(Cc1ccco1)C1CCS(=O)(=O)C1
