Text Solution
Verified by Experts
The correct Answer is:
C
Encouraging to plant more trees we ensure clean and pollution free environment and it also provide bio-mass fuel. Gobar-gas is made from the decomposition of cow dung, crops, vegetable wastes, etc., decompose in the absence of oxygen. The main ingredient of bio-gas is methane. It burns without smoke, leaves no residue like ash in wood, charcoal and coal burning. Bio-mass is living matter or its residues and is a renewable source of energy. Thus, part (c ) is the incorrect statement.
