A pressure cooker reduces cooking time for food because :
A
heat is more evenly distributed in the cooking space
B
boiling point of water involved in cooking is increased
C
the higher pressure inside the cooker crushes the food material
D
cooking involves chemical changes helped by a rise in temperature

boiling point of water involved in cooking is increased
Explanation
Solution
High pressure inside the cooker increases boiling point, thus heat consistently given is used up by food material instead in boiling and constant boiling evaporation.
