{'kidney': [2, 0, 0, 0], 'blood ph': [1, 0, 0, 0], 'metabolic': [1, 0, 0, 0], 'function': [11, 2, 3, 13], 'blood': [5, 0, 0, 1], 'osmotic pressures': [1, 0, 0, 0], 'regulation': [3, 1, 2, 9], 'body': [27, 3, 23, 37], 'antibodies': [4, 0, 1, 1]}

The correct answer is option 3: Production of antibodies. The kidney performs several functions to maintain homeostasis in the body. It regulates the pH of the blood by excreting excess hydrogen ions or bicarbonate ions. The kidney also removes metabolic wastes from the body, such as urea and creatinine, through the process of filtration and excretion. Additionally, the kidney plays a role in regulating the osmotic pressures of the blood by controlling the reabsorption of water and solutes. However, the production of antibodies is not a function of the kidney. Antibodies are produced by specialized cells of the immune system, mainly in the bone marrow and the lymph nodes. Therefore, option 3 is the correct answer as it is not a function performed by the kidney.
