Best Answer Explained in Below-:

The question revolves around the word '’র্ক', which can be analyzed to identify its distinct morphological components. In Bengali, words are often formed by combining roots and suffixes, and understanding these components is key to grasping the formation of the word.

The correct answer, A) ক + র, reflects the basic structure where 'ক' (pronounced "ka") is the root, and 'র' (pronounced "ro") serves as a suffix modifying the root. '’র্ক' can be recognized as a compound of 'ক' and 'র', where 'ক' pertains to the basic meaning or action in the word, and 'র' provides an additional grammatical function, like possession or association.

The other options incorporate either extraneous vowels or misplaced components that do not accurately depict the word's morphological structure. For example, options C and D add vowels without justification in the context of the original word. Hence, the analysis leads to the conclusion that A) ক + র is indeed the correct breakdown of ‘’র্ক’, confirming its distinct and meaningful segmentation in Bengali morphology.
