Explanation:

This insightful statement about the Indian Constitution's unique nature, balancing its amendability with its foundational principles, was made by K.C. Wheare, a renowned constitutional expert. He also famously described the Indian Constitution as 'quasi-federal'. B.R. Ambedkar was the chief architect of the Constitution. M.V. Pylee and Alexanderowicz are other notable scholars of constitutional law, but this specific quote is attributed to Wheare.
