Suppose that Protein J which is a hypothetical protein kinase receptor was determined to be related to the progression of cancer through its activation. It was also determined that the protein exists in the active and inactive forms. The said active form is highly similar to the Protein K's conformation. Ligands A, B, and C, which are lead inhibitor compounds, were optimized to inhibit Protein J. The affinities of the ligands are shown in the table. Kp values Active Protein J Inactive Protein J Protein K Ligand A 10 mM 20 nM 5 mM Ligand B 20 nM 10 mM 15 nM Ligand C 20 nM 15 nM 15 nM Question: a. Which of the ligands, based on the table, has the highest specificity in binding to the target Protein J?
