B Correct answer
Explanation

Wood has a calorific value of approximately 17 kJ/g, which falls within the typical range of 15-20 kJ/g for dry wood. Option B correctly states this value. Option A (33 kJ/g) is too high and closer to coal. Option C (3.7 kJ/g) is far too low. Option D (1.7 kJ/g) is unrealistically low for wood. The 17 kJ/g value represents the average energy content of good quality dry wood fuel.
