Answer:
Correct Answer:
(C) the pipe passed through a diamond-stability field and thus may contain diamonds
Explanation:
The passage from which the question was gotten is attached below:
<u>Diamonds are almost impossible to detect directly</u>
<u></u>
Diamonds are almost impossible to detect directly because they are so rare: very rich kimberlite Line pipes, the routes through which diamonds rise, may contain only three carats of diamonds per ton of kimberlite. Kimberlite begins as magma in Earth's mantle (the layer between the crust and the core).
As the magma smashes through layers of rock, it rips out debris, creating a mix of liquid and solid material. Some of the solid material it brings up may come from a so-called diamond-stability field, where conditions of pressure and temperature are conducive to the formation of diamonds.
If diamonds are to survive, though, they must shoot toward Earth's surface quickly. Otherwise, they revert to graphite or burn. Explorers seeking diamonds look for specks of indicator minerals.

Prices of steel and aluminium prices will depend on the market demand and supply.
<u>
Explanation:
</u>
The manufacturing industries are mainly depending on the steel as major source of raw material. The main reason for the demand of the steel will increase if the infrastructure development in the society. And it also reflects the economic boom happening in the society.
So if the demand of the steel increases because of various reasons like wage rise and demand for raw material like iron ore. In the event of price rise of steel the aluminium will be the next alternate for steel in the infrastructure development. So, if there is demand for steel arises automatically the aluminium prices will also increase.
As the nebular cloud condenses and its own gravitational attraction collapses it, heat and energy build up creating "nuclear fusion".
Nuclear fusion, process by which nuclear reactions between light components form heavier components. In situations where the interfacing cores have a place with components with low nuclear numbers (e.g., hydrogen or its isotopes deuterium and tritium), considerable measures of energy are discharged.
