Task: Answer the multiple choice question.
Question: Which drug has a 6.334\% 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 COc1ccc(OCC(=O)Nc2cc(OC)cc(OC)c2)cc1
b O=C(CN(C(=O)CCC(=O)Nc1nccs1)c1ccccc1F)NCC1CCCO1
c COCCNC(=O)C(c1ccc(C)o1)N(C(=O)c1snc(C(N)=O)c1N)c1cc(C)cc(C)c1
Answer: b. O=C(CN(C(=O)CCC(=O)Nc1nccs1)c1ccccc1F)NCC1CCCO1
