Statement I is correct because severe ulcerative colitis is defined clinically by having more than four bowel motions per day along with systemic signs like fever, tachycardia, or anemia.
This matches standard diagnostic guidelines for severe cases.
Statement II is also correct — acute pancreatitis is characterized by sudden onset abdominal pain, often radiating to the back, and is confirmed by elevated pancreatic enzymes (amylase or lipase) in blood or urine.
These enzyme levels reflect inflammation and pancreatic cell damage.
Therefore, both statements are factually accurate.
So, option (1) is the correct answer.
