The correct option is (a).
Explanation
The Upanishads, composed towards the end of the Vedic period (c. 700–500 BCE), focus on philosophical inquiries regarding the soul (Atman) and the universal spirit (Brahman). While the intellectual discourse was predominantly led by the upper varnas, the texts record specific instances of participation by women and individuals from humble backgrounds.
Statement-wise Analysis
- Statement 1 is Correct: The majority of Upanishadic thinkers mentioned in the texts were men, specifically belonging to the Brahmin (priestly) and Kshatriya (royal/raja) classes. Kings like Janaka of Videha were active participants in philosophical debates.
- Statement 2 is Correct: There were women thinkers, such as Gargi Vachaknavi, who was renowned for her learning. She famously participated in debates held in royal courts, such as the assembly of King Janaka, as recorded in the Brihadaranyaka Upanishad.
- Statement 3 is Correct: Satyakama Jabala is a prominent figure in the Chandogya Upanishad. He was named after his mother, Jabala, who was a slave woman. Despite his background, he was accepted as a student by the Brahmin teacher Gautama because of his commitment to speaking the truth.
- Statement 4 is Incorrect: While it is true that poor people rarely participated in these discussions, they were not "strictly prohibited from ever participating." The acceptance of Satyakama Jabala serves as a famous exception to the general norm, proving that intellectual circles were not entirely closed based on economic status if the individual demonstrated spiritual aptitude.
Key Takeaway: The Upanishadic intellectual tradition was largely aristocratic and male-dominated, yet it possessed a degree of fluidity that allowed for exceptions like Gargi (women) and Satyakama Jabala (non-elite background) based on merit and learning.
