<span>Extraction of DNA is important because of many reasons. With the ability to remove DNA from an organism, scientists can observe, manipulate, and classify the DNA.
Scientists can identify genetic disorders or diseases from studying DNA.
Scientists can possibly find cures for these causes by manipulating or experimenting with this DNA.
Scientists can accurately sort organisms into classes because of DNA uniqueness. If we didn't have DNA extraction, it would be a lot harder to decide which organisms are different from each other.
Scientists can genetically engineer some organisms to produce beneficial things. A common example is that of insulin. Scientists can genetically engineer insulin production so that people with diabetes can live longer.</span>

The mantle being made of nickel and iron is the correct statement about the geosphere and is denoted as option B.
<h3>What is Geosphere?</h3>
This is referred to the solid part of the earth and consists of rocky materials present in it.
The geosphere has the mantle which is made up of materials such as iron and nickel which are metals and are responsible for their rigid solid structure thereby ,making it the most appropriate choice.
