In the following questions, a grammatically correct and meaningful sentence is given which is divided into four parts namely (A) ,(B) ,(C) and (D) You have to arrange the four parts to make a contextually and grammatically meaningful sentence. If no such rearrangement is possible mark (e) as your answer i.e. 'No rearrangement required'.

is becoming very prevalent (A) / nowadays online education (B) / is village or city (C) / everywhere whether it (D) .

The correct option is BADC.

To form a grammatically correct and meaningful sentence, let's analyze the given parts:

1. Part (B): "nowadays online education" serves as the main subject of the sentence, introducing what the sentence is discussing.
2. Part (A): "is becoming very prevalent" functions as the main verb phrase describing the state or action of the subject ("online education is becoming very prevalent"). Combining B and A gives: "nowadays online education is becoming very prevalent".
3. Part (D): "everywhere whether it" acts as an adverbial modifier indicating the extent ("everywhere") and introducing a conditional clause ("whether it"). Connecting this to part A forms: "...is becoming very prevalent everywhere whether it...".
4. Part (C): "is village or city" completes the conditional clause introduced by part D ("whether it is village or city").

Putting all the parts together in the sequence B - A - D - C yields the complete, coherent sentence:
"Nowadays online education is becoming very prevalent everywhere whether it is village or city."

Therefore, the correct arrangement is BADC.
