Task: Answer the multiple choice question.
Query: Which drug has a 13.143\% 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(COC(=O)c1ccccn1)Nc1nccs1
[b] C=C(C)CNC(=S)N/N=C/c1ccc(NC(C)=O)cc1
[c] c1ccc(CCCN2CCN(c3ccccc3)CC2)cc1
Answer: a. O=C(COC(=O)c1ccccn1)Nc1nccs1
