. . . . . . . . wheat of . . . . . . . . Punjab is liked by all.

Solution (By Examveda Team)

The noun "wheat" refers to a specific kind of wheat (from a particular region), so it takes the definite article "the".

"Punjab" is a proper noun referring to a specific place, and when indicating a particular region known for something, it is often preceded by "The".

Thus, the correct sentence becomes: "The wheat of The Punjab is liked by all."

Other options are incorrect because they either use indefinite articles or omit necessary definiteness.

Hence, the correct answer is the, The.
