Detailed Solution:
The correct answer is “K.C Wheare”.
K.C. Wheare is credited with describing India's federal system as "quasi-federal."
He analyzed the Indian Constitution and concluded that while it possesses many federal features, such as a written constitution, division of powers, and independent judiciary, it also exhibits unitary characteristics, such as a strong central government and the power of the Union to amend the Constitution.
This combination of federal and unitary elements led Wheare to characterize India's system as quasi-federal.
