Problem statement: Answer the multiple-choice question.
Question: Which drug exhibits a 5.664\% 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 other words.
Options:
a O=C1C2CCc3ccccc3C2N1c1ccccc1
b COc1cccc(CNC(=O)CN2C(=O)CC(c3ccccc3)=Nc3ccccc32)c1
c COc1ccc(NC(=O)C(Sc2nnc(-c3ccncc3)n2-c2ccccc2C)c2ccccc2)cc1Cl
Answer: a. O=C1C2CCc3ccccc3C2N1c1ccccc1
