The stories of Shvetaketu and Nachiketa teach us the worth of

The correct answer is B, Asking questions in pursuit of knowledge. Both Shvetaketu and Nachiketa are young seekers in the Upanishads whose stories show that knowledge is won by asking questions and refusing easy answers. In the Chhandogya Upanishad, Shvetaketu returns proud after twelve years of study, and his father Uddalaka Aruni asks whether he knows that by which everything is known. Through patient questions and examples, such as salt dissolved in water, the father leads him to the teaching "Tat tvam asi", "That thou art". In the Katha Upanishad, the boy Nachiketa goes to Yama, the god of death, and refuses wealth, long life and pleasures until Yama answers his question about what happens after death and the nature of the self. Option A is wrong because the stories praise questioning, not blind obedience; Nachiketa even questions his own father's gifts. Option C is wrong because the stories are not about friendship. Option D is wrong because they are about inner knowledge, not physical work or health. Exam tip: Shvetaketu, Chhandogya Upanishad, "Tat tvam asi"; Nachiketa and Yama, Katha Upanishad.
