Answer:
Option (B)
Explanation:
For an organism to get preserve and form fossil, the organism must be comprised of a hard part and they should be immediately buried by the sediments after their death. The body of the organism must be detached from the oxygenated environment so that the body does not get damaged.
Mudflats usually refers to the coastal wetland areas that are commonly formed in the inter-tidal zone. They are also considered as the tidal flats. These mudflats are comprised of fine sediments that are carried from other places and are rich in organic matter and there is low or absence of oxygen. This helps in the preservation of fossils.
For example, clams with calcite shells that lived on the mudflat are most likely to be preserved in geological history.
Hence, the correct answer is option (B).

Answer:
<u>Instead of Helium and Hydrogen there are heavier elements in inner planets like Nitrogen and oxygen.</u>
Explanation:
- As the inner planets like Mercury, Venus and Mars and earth have a solid surface which is separated by the Sharpe atmosphere, and their gravity is too low to hold these light gases.
- Uranus is primarily composed of gases and ice of which 83% is hydrogen and 15% helium and rest are trace gases. As in the early composition of the atmosphere, the inner planets like the earth had a solid atmosphere composed of solid silicates elements like magnesium, iron, calcium, and potassium.
- As the earth has a highly unstable atmosphere only carbon, nitrogen and oxygen combined in lightning occur. And planet mercury has no atmosphere thus gravity is too low to hold any gas.
