The question and choices given are a bit tricky. The correct answer is A because the language of (iv) is deceptive and says "new trees will grow quickly to replace the burnt ones". You have to understand that "new trees" won't grow quickly, you can only sow small plants not trees.

B IS THE CORRECT ANSWER AS BURNING OF WASTE CROPS AFTER HARVESTING OF GRAINS IS STANDARD METHOD OF INCREASING SOIL FERTILITY
