'Indian nationalism in the middle of the 19th century was in Embryonic stage' was a historian with regard to the fact

The correct answer is (D) Sir John Lawrence and Seale.

• Sir John Lawrence and Sir John Seeley were colonial historians who argued that Indian nationalism was in an embryonic stage during the mid-19th century. They maintained that India was not a nation in the modern sense but a collection of diverse entities held together only by British administrative and military power.
• This historiographical perspective characterizes the 1857 Revolt and mid-19th-century political activities as fragmented struggles lacking a unified national consciousness, often dismissing them as 'mutinies' or 'local uprisings' rather than organized nationalist movements.
• Option (A) includes R.C. Majumdar, who famously viewed the 1857 event as neither first, nor national, nor a war of independence, but he is distinct from the specific grouping of Lawrence and Seeley regarding the 'embryonic stage' theory. Options (B) and (C) refer to British officials or historians primarily known for their military roles or accounts of specific rebellion incidents rather than the broader structural theory of the evolution of Indian nationalism.
