Problem statement: Answer the MCQ question.
Question: Which compound exhibits a 13.262\% human ether-à-go-go related gene (hERG) inhibition at 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any additional words.
Options:
a: CC(C)c1cc(C(=O)N2CCCC(CCC(=O)N3CCN(c4ccccn4)CC3)C2)no1
b: O=C1NC(C(=O)O)=CC(c2cccc(Cl)c2Cl)N1
c: Cc1c(Cl)c([N+](=O)[O-])nn1CCCC(=O)Nc1c(C)n(C)n(-c2ccccc2)c1=O
d: O=C(CCCSc1nnc(SCCCC(=O)c2ccc(F)cc2)s1)c1ccc(F)cc1
Answer: b. O=C1NC(C(=O)O)=CC(c2cccc(Cl)c2Cl)N1
