Correct answer is (b) False

To explain I would say: The given statement is false. Cullet also reduces the amount of dust and other particulate matter that often accompanies a batch made exclusively from new raw materials.  The use of cullet is economically desirable since less energy is required to melt cullet than new raw materials.
