Ans a ) Granular Mucosa- This is a feature of ulcerative colitis ( Table 49-7 Sabiston 20) 

The typical gross appearance of ulcerative colitis is hyperemic mucosa.

Friable and granular mucosa is common in more severe cases, and ulceration may not be readily evident. ( Saby 1340) 

IN Crohn disease - Microscopically, there are focal areas of chronic inflammation involving all layers of the intestinal wall with lymphoid
aggregates. Non-caseating giant cell granulomas are found in 60% of patients and when present clearly allow a confident diagnosis of CD.

Interferon gamma is for subclinical infection

BMFT shows subhepatic caecum
