Problem statement: Answer the multiple choice question.
Query: Which drug has a 4.045\% hERG inhibition at a concentration of 1uM?
Constraint: You must select none, one or more options from a, b, c, or d without using any other words.
Options:
[a] COC(=O)c1cn(NC(=O)c2cccc(F)c2)c(=O)c2ccccc12
[b] O=C(O)c1cccc(COc2ccc3c(c2)CCC3)c1
[c] O=C(O)CC/C(=N\NC(=O)CNC(=O)c1cccc(Cl)c1)c1ccccc1
[d] Cc1ccc2c(COC(=O)CNC(=O)c3ccccc3)cc(=O)oc2c1
Answer: c. O=C(O)CC/C(=N\NC(=O)CNC(=O)c1cccc(Cl)c1)c1ccccc1
