Solution

The correct options are
A
Combustion of fuels

B
Transpiration by plants

D
Respiration by living organisms

Water is added to the atmosphere by natural processes such as:-

(a) Combustion of fuels:- Burning of fuels in presence of oxygen produces carbon dioxide, water, and heat/light energy

Example:- $C H_{4} (g) + O_{2} (g) \to C O_{2} (g) + H_{2} O (g) + h e a t a n d l i g h t$

(b) Respiration by living organisms:- When living organisms respire (inhale oxygen) then glucose breakdowns into carbon dioxide, water, and energy (ATP)

$C_{6} H_{12} O_{6} (s) + 6 O_{2} (g) \to 6 C O_{2} (g) + 6 H_{2} O (g) + E n e r g y$

(c) Transpiration by plants:- It is evaporation of water from the plant leaf.

While condensation is not the source of water addition to nature but a process that converts water vapour to water.
