<h3><u>Answer;</u></h3>
D) India was a separate continent until forty-five million years ago.
<h3><u>Explanation</u>;</h3>
- <em><u>Continental drift serves as one of the evidence of evolution. Different kinds of animals and plants live in different parts of the world. This is true now, and it was true in the past. </u></em>

Answer: The correct answer is salt.
A compound is a chemical substance which is formed by the combination of two or more elements, joined together in a fixed proportion.
Salt is a chemical compound which is formed by the reaction of an acid with a base. For example- NaCl ( sodium chloride) is a common salt. It is formed by the combination of two elements. Therefore, salt is a compound.
On the contrary, Phosphorous (P), sulfur (S) and Oxygen (O₂) are composed of a single element. Therefore, they are not compounds.
Thus, the correct answer for the compound is Salt
