List I: Concept	List II: Description
(a) Turiyavastha	(iv) Steady state of consciousness when essential nature of atman is experienced
(b) Prajnavastha	(iii) State of super consciousness when dichotomy between grossness and subtlety disappears
(c) Swapanvastha	(ii) Subconscious faculty concerned with the subtler aspects of human knowledge and experience
(d) Jagratavastha	(i) The state of normal consciousness concerned with material world

Correct option is B

The four states of consciousness in Vedantic psychology (from Mandukya Upanishad) are hierarchically arranged. (a) Turiyavastha is the fourth transcendental state where the essential nature of Atman (Self) is experienced (iv), representing pure consciousness beyond subject-object duality. (b) Prajnavastha is the deep sleep state characterized by super consciousness where the dichotomy between gross and subtle dissolves (iii) into undifferentiated awareness. (c) Swapanvastha is the dream state involving subconscious processes that engage with subtle aspects of knowledge and mental impressions (ii). (d) Jagratavastha is the waking state characterized by normal consciousness engaged with the external material world (i). Option 2 correctly maps these consciousness states according to classical Indian psychology frameworks.
