In the question below, a grammatically correct and meaningful sentence is given which is divided into four parts, (A), (B), (C) and (D). Arrange these four parts to make a contextually and grammatically meaningful sentence. Choose the option which gives the correct sequence of the parts. If the sentence is already arranged in the correct sequence, mark option " No rearrangement required " as the answer.

(A) evapotranspiration is 

(B) it to estimate how much 

(C) water their crops need to be fed 

(D) relevant for farmers, who use 

Correct option is D

Correct Answer: D) ADBC

Formed Sentence:

Evapotranspiration is relevant for farmers, who use it to estimate how much water their crops need to be fed.

Why This Sequence Is Correct

1.       (A) must begin the sentence because it introduces the subject “evapotranspiration.”

2.       (D) logically follows by explaining why it is relevant and introduces the clause about farmers.

3.       (B) continues the clause by referring back to “it” (evapotranspiration).

4.       (C) completes the idea by specifying what is being estimated — the amount of water crops need.

The sentence becomes grammatically complete and contextually meaningful.
