Task: Answer the multiple choice question.
Question: Which drug has a 12.960\% 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] COC(=O)C1=C(C)Nc2sc(C(N)=O)c(N)c2C1c1ccncc1
[b] CCCCS(=O)(=O)N1CCC(C(=O)NCC2CCCO2)CC1
[c] O=C(Nc1ccc(-c2nnn(CC(=O)N3CCN(C(=O)c4ccco4)CC3)n2)cc1)c1ccccc1F
Answer: a. COC(=O)C1=C(C)Nc2sc(C(N)=O)c(N)c2C1c1ccncc1
