Assertion [A] : Malpighian tubules are excretory organs projecting from the colon of the digestive system
Reason [R] : The nitrogenous excretory product is Uric acid.
Assertion [A] is True and Reason [R] is True, but is not a correct explanation to [A]
Even though Malpighian tubules are a part of the digestive system, they perform a major role in converting absorbed nitrogenous excretory products into Uric acid. Therefore, even though both the assertion and the reason are true, they are true in their own pretext, and the reason is not an explanation of the assertion
