Solution
The correct option is B Diatomaceous earth
- Diatoms
are single-celled algae that inhabit either fresh or marine aquatic habitat.
Their skeleton comprises of hard natural substance silica.
- Diatomaceous earth
is made from the fossilized remains of diatoms, formed due to depositions of
their siliceous cell walls at the sediments of the water bodies which diatoms
used to live in large numbers.
- It is naturally obtained in the form of soft
rock that can be easily crumbled into a fine powder of off-white color.
Diatomaceous earth has a good number of commercial utilities. It is used in
agriculture, cosmetic products, paint industries, pest control, etc.
- It can be
used as a flattening agent of paint. Diatomaceous earth when added to paints,
the protruding parts of the diatoms diffract light and adds a uniform sheen to
the surface.
- This increases the visibility of the painted surface during the
night.
