• D. If both the assertion and reason are false

Answer 1

The correct option is B If both the assertion and the reason are true but the reason is not correct explanation of the assertion.

On the basis of presence of tiny granules and number of lobes in nucleus of their cytoplasm , white blood cells are dived into two group

(i) Granulocytes Contain tiny granules and 2-5 lobed nucleus in their cytoplasm.They are eosinophils, basophils and neutrophils.

(ii) Agranulocytes Have no cytoplasic granules in their cytoplasm and their nuclei are also undivided .

They are Lymphocytes and Monocytes.

Therefore both assertion and reason are true.

So, the correct answer is 'If both the assertion and the reason are true but the reason is not correct explanation of the assertion.'
