Who among the following pairs of Vedantins, do not justify the concept of Jivanmukti?

Answer: Option B

The correct answer is Option B: Ramanuja and Madhya.

Here's why:

Jivanmukti refers to the state of liberation while still living.
It means attaining enlightenment and freedom from suffering even before physical death.

Shankara, Vacaspati, and Prakasatman are all proponents of Advaita Vedanta, which strongly supports the concept of Jivanmukti.

Ramanuja and Madhva, on the other hand, belong to Vishishtadvaita and Dvaita Vedanta respectively.
These schools emphasize devotion and a qualified difference between the individual soul and Brahman (the ultimate reality).
They believe liberation is primarily attained after death (Videhamukti) rather than during life (Jivanmukti).
Therefore, Ramanuja and Madhya do not justify the concept of Jivanmukti in their respective philosophies.
