Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Neutrophils and monocytes both destroy foreign organisms entering the body and belong to the same main category of leucocytes. Reason (R): Neutrophils possess specific granules in their cytoplasm, whereas monocytes lack these granules and have a kidney-shaped nucleus. In the light of the above stat
Options
- ABoth Assertion and Reason are correct and Reason is the correct explanation for Assertion
- BBoth Assertion and Reason are correct but Reason is not the correct explanation for Assertion
- CAssertion is correct but Reason is false
- DAssertion is false but Reason is correct
Correct answer
D. Assertion is false but Reason is correct
Step-by-step solution
Assertion (A) is false because although both neutrophils and monocytes are phagocytic cells that destroy foreign organisms, they belong to two different main categories of leucocytes. Neutrophils are granulocytes, while monocytes are agranulocytes. Reason (R) is correct because neutrophils have granules in their cytoplasm (hence classified as granulocytes), whereas monocytes lack these granules (hence classified as agranulocytes) and possess a characteristic kidney-shaped nucleus. Answer: Assertion is false but Rea
