Answer:

Option (C)

Explanation:

The O stars are the hottest of all the stars which have a maximum temperature of approximately 40,000 K. They appear to be bluish in color. The hydrogen present on the surface of this type of stars are fully ionized, due to which it's surface temperature is extremely high. Some of the visible elements are also present such as oxygen, silicon, helium, and nitrogen.

These stars can survive for a period of nearly 10 billion years. These are the main sequence stars with high luminosity.

Thus, the correct answer is option (C).

Answer:

Corals reef is a underwater ecosystem that builds on limestone beds, CaCo3

Explanation:

They have exoskeletons made up of limestones and its possible that the corals might have moved offshore with changes in the sea levels as, he finds an abundance of large clam fossils, that produce within the interlocking of limestone section.

Since the clam is made up primarily of coral fragments its possible that the corals might have buried under the landmass when the upliftment was completed.

The skeletal remains of the coral polyps that are now stratified in the rocks are suggestive of reef formation around the landmass earlier period and these were mostly found in tropical oceans.
