D is the most suitable part to begin the sentence with, as it introduces the subject 'Mahabharata'. B must follow D, as it has a verb 'narrates' that agrees with the singular subject 'Mahabharata'. C must follow B, as it has a preposition 'between' that indicates the relationship between two groups of cousins. A must follow C, as it has an article 'an' and a noun phrase 'ancient Indian epic poem' that describes what Mahabharata is. E must follow A, as it has another preposition 'in' that indicates where the struggle took place.
Therefore, the correct order is DBCAE.
Hence, option (b) is the correct answer.
The correct sentence is: Mahabharata narrates the struggle between two groups of cousins in an ancient Indian epic poem in the Kurukshetra War.
