Best Answer Explained in Below-:

The correct sentence is B) "Paper is made from wood." This option is grammatically correct and accurately reflects the relationship between paper and its raw material, wood.

In English, the phrase "made from" is commonly used to indicate that one material is derived from another and emphasizes the transformation process. In this case, wood undergoes a series of processes, such as pulping and refining, to create paper, so it's appropriate to say that paper is "made from" wood.

Let's look at the other options to understand why they don't work:

A) "Paper is made of wood" is technically acceptable but is less precise. While it implies that wood is a component of paper, it doesn't convey the transformation that happens in the paper-making process.

C) "Paper is made by wood" is incorrect because it suggests that wood itself is doing the action of creating paper, which is not the case.

D) "Paper made on wood" is grammatically incorrect and doesn’t convey a clear meaning related to the creation of paper.

Thus, option B articulates the process clearly and accurately, making it the best choice.
