Task: Answer the MCQ question.
Question: Which compound exhibits a 4.343\% human ether-à-go-go related gene (hERG) inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CCOC(=O)N1CCN(C(=O)C(=O)NNC(=O)COc2ccc(Cl)cc2)CC1
b: CNC(=O)c1cccc(NC(=O)c2cc(-c3ccccc3)nc3c2cnn3C(C)C)c1
c: COc1ccc2c(c1)C(c1ccc(N3CCOCC3)cc1)=NNC(c1cccnc1)=N2
d: O=C(NCc1ccccc1Cl)NC(=O)c1csc([N+](=O)[O-])c1
Answer: d. O=C(NCc1ccccc1Cl)NC(=O)c1csc([N+](=O)[O-])c1
