Education enables a man

Option A is correct. The question asks about education in its classical sense: it draws out what is already latent in a person, namely intellect, character and the inner self. Vivekananda's idea that education is the manifestation of the perfection already in man captures this well.

Why the others fail:

• B: Gardening is a vocation. Education may help one pursue it, but producing gardeners is not its defining purpose.
• C: Physical strength comes from exercise, diet and training. Physical development is part of holistic growth, but it is not what education, in this sense, enables.
• D: Success depends on opportunity, effort and social context. Education can contribute to it, but it is an outcome, not the purpose.

Core concept: education as self-realisation, the basis of the Upanishadic idea of vidya and of the thinking of Tagore and Gandhi on educating the whole person. For Mains (GS-IV, ethics), it links to the debate over whether education should produce only employable persons or fully developed human beings. NEP 2020's emphasis on holistic development keeps this view alive in policy language.

Trap: Aspirants often pick D because modern education is judged by careers. The question asks what education does at its core, not what it may lead to.
