Problem statement: Answer the MCQ question.
Query: Which compound has a 20.397\% 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) COC(=O)CN(c1ccc(Cl)cc1C)S(C)(=O)=O
b) COc1cc(NC(=O)CN2C(=O)NC(C)(c3ccc(OC(F)F)cc3)C2=O)cc(OC)c1OC
c) NC(N)=NCC(O)CN(c1ccccc1)c1ccccc1.O=S(=O)(O)O
Answer: a. COC(=O)CN(c1ccc(Cl)cc1C)S(C)(=O)=O
