Calorific value of dry wood may be around __________ Kcal/kg.

Answer: Option D

The calorific value of a fuel is the amount of heat energy released during its combustion.

For dry wood, the calorific value is typically around 5000 Kcal/kg, making it a good source of energy for combustion processes.

This value can vary slightly depending on the type of wood and its composition, but 5000 Kcal/kg is a common average used in calculations and assessments.
