During urine formation, the tubular cells secrete substances like H+,K+  and ammonia into the filtrate. Tubular secretion is also an important step in urine formation as it helps in the maintenance of ionic and acid base balance of body fluids.

Potassium is secreted in tubules and, sodium is reabsorbed. Otherwise it will cause a condition called hyperkalemia.

Hydrogen is secreted into filtrate and is important to maintain blood pH.

Hence option C is correct.
