Solution
The passage says:
"The Deccani style of painting has been in Indo-Persian art for a long time."
It also says:
"Art historians acknowledged its uniqueness but failed to recognise it as a full-fledged school which was sustained by a class of rulers..."
And:
"The kingdoms of Bijapur, Golconda and Ahmadnagar developed highly sophisticated and distinct schools of court painting."
Thus NTA treats A, B and D as correct. C is incorrect because the passage clearly says portraiture and representations of historical and religious figures are also found in other schools. Therefore, Option 2 is correct.
Note: Statement A is loosely worded because the passage says historians did acknowledge the style's uniqueness; what they failed to recognise was its status as a full-fledged school.
