Complete the following sentences.

Which of the following is not a tree?

The correct answer is Hilsa.

Detailed Explanation:

In this question, we are asked to identify which of the following is not a tree. The term "tree" refers to a large, perennial plant with a single stem or trunk, supporting branches and leaves. Trees are an essential part of the ecosystem, providing oxygen, shelter, and food.

To analyze the options, let’s consider what each option represents:

• Hilsa: Hilsa is a type of fish, and as such, it is not a tree. It belongs to the aquatic ecosystem and is widely known in the context of marine biology.
• Other options: If other options refer to actual trees like Banyan, Oak, or Pine, they are all trees, and therefore, they do not fit the question “Which of the following is not a tree?”.

Hence, Hilsa is the answer because it does not fit the definition of a tree. In this context, we can conclude that Hilsa is the correct choice when you are asked, “Which of the following is not a tree?”

So, in answer to the question: Which of the following is not a tree?, Hilsa is the correct and valid response.
