Problem statement: Answer the MCQ question.
Question: Which compound exhibits a -1.679\% 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 other words.
Options:
[a] O=C(Cc1cc(=O)oc2cc(O)ccc12)NC(Cc1ccc(Cl)cc1)C(=O)O
[b] COc1ccc(-c2oc(NC(C)=O)c(C#N)c2-c2ccc(OC)cc2)cc1
[c] COc1cc(OC)c(NS(=O)(=O)c2c(C(=O)N3CCCCC3)c(C)n(C)c2C)cc1Cl
[d] Cc1cc(=O)oc2cc(OC(C)C(=O)Nc3nccs3)ccc12
Answer: b. COc1ccc(-c2oc(NC(C)=O)c(C#N)c2-c2ccc(OC)cc2)cc1
