Problem statement: Answer the multiple choice question.
Query: Which compound has a 4.603\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, or c without using any other words.
Options:
[a] O=C(OCc1ccccc1)c1ccc2c(c1)-c1ccccc1C2=O
[b] O=C(O)C(=O)O.Oc1ccccc1CN(CCc1ccccc1)Cc1ccccc1
[c] CCCNC(=O)CC(NS(=O)(=O)c1ccc(Cl)cc1)c1ccco1
Answer: a. O=C(OCc1ccccc1)c1ccc2c(c1)-c1ccccc1C2=O
