Who among the following leaders defined Hindutva as the basis of Indian nationhood?

V. D Savarkar

The correct answer is Option (4) → V. D Savarkar

Hindutva was popularised by Vinayak Damodar Savarkar, as the basis of Indian nationhood. It basically meant that to be an Indian, one must accept India as their ‘fatherland’ (pitrubhu) as well as their holy land (punyabhu). Believers of ‘Hindutva’ argue that a strong nation can be built on the basis of a united national culture. They also believe that in the case of India, Hindutva can provide this base.
