Hint: Paper is a thin sheet material produced by mechanically and or chemically processing cellulose fibers derived from wood, rags, grasses or other vegetable sources in water, followed by pressing and drying.
Recycling: It means to reuse waste material by converting it into something new.
An example of recycling is aluminum and steel cans.

Complete answer:
 Recycling: It is the process by which waste paper is converted into new paper products.
It saves waste paper by producing methane.
Because paper fiber contains carbon
Recycling keeps the carbon locked up for longer and out of the atmosphere.
After repeated processing the fibers become too short for the production of new paper.
There are three categories of paper that can be used as feedstocks for making recycled paper
They are:
1. Mill broke
2. Pre-consumer waste
3. Post consumer waste.
Mill broke is paper trimmings and other paper scrap from the manufacture of paper and is recycled in a paper mill.
Pre-consumer waste is a material which was discarded before it was ready for consumer use.
Post-consumer waste is material discarded after consumer use, such as old corrugated containers (OCC), old magazines, and newspapers.
The industrial process of removing printing ink from paper fibers of recycled paper to make deinked paper is called deinking.

So, the correct option is option D. All of the above.

Note: The three R's – reduce, reuse and recycle –
They help to limit the amount of waste we throw away.
They conserve natural resources and energy.
Reduce: It means we should limit the use of particular resources.
Reuse: It means we need to re use the particular resource so that wastage is minimum.
Recycle: It means conversion of a product into a new product.
