Assertion: Family planning is an action plan to attain reproductive health among people.
Reason: Improved programmes covering reproduction related area were propagated by RCH to create awareness among people.
Both assertion and reason are true, and the reason is the correct explanation for the assertion.
Both assertion and reason are true, but the reason is not the correct explanation for the assertion.
Assertion is true, but the reason is false.
Both assertion and reason are false.
Correct Answer
Detailed Explanation
The assertion that "Psilotum is a living fossil" is accurate because Psilotum, a genus of primitive vascular plants, has characteristics that have remained relatively unchanged for millions of years, reflecting its ancient lineage. The reason stating "Equisetum is heterosporous pteridophyte" is incorrect because Equisetum, commonly known as horsetails, is actually homosporous, producing only one type of spore. Therefore, while both statements are true, the reason does not correctly explain the assertion, making option A the appropriate choice. Options B and C are incorrect as they misrepresent the truth of the statements, and option D is false since the assertion is indeed correct.
