Problem statement: Answer the MCQ question.
Query: Which drug exhibits a -1.806\% 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] C/C(CCN1CCc2nc(-c3ccccc3)c(-c3ccccc3)cc2C1)=N\O[C@@H](C)c1cn([C@H](CO)Cc2ccccc2)nn1
[b] CN(Cc1ccc(Cl)c(Cl)c1)C(=O)CN1C(=O)NC2(CCCC2)C1=O
[c] CN(CC(=O)Nc1ccccc1Cl)C(=O)c1cc(-c2cccs2)nn1-c1ccccc1
Answer: a. C/C(CCN1CCc2nc(-c3ccccc3)c(-c3ccccc3)cc2C1)=N\O[C@@H](C)c1cn([C@H](CO)Cc2ccccc2)nn1
