Step 1: Understanding the Concept:
Chapter 12 of the Bhagavad Gita is titled Bhakti Yoga. It contrasts the worship of the Unmanifested Brahman (Nirguna) with the worship of the Personal God (Saguna). Lord Krishna provides the characteristics and the results for practitioners of both paths. For examinations focusing on Puranetihas and Sanskrit, memorizing the literal flow of these verses is essential as they represent the technical definitions of Bhakti and Yoga.
Step 2: Detailed Explanation of Verse Completion:
1. A-IV: This comes from Verse 12.3. Krishna describes the Unmanifest: "But those who worship the Imperishable, the Indefinable... the All-pervading, the Inconceivable, the Unchanging, the Immovable, and the Eternal (sarvatragam-achintyancha kutastham-achalam dhruvam)."
2. B-I: This is Verse 12.4, continuing from the previous verse: "Having restrained all the senses, being even-minded everywhere... they also reach Me, being devoted to the welfare of all beings (te prapnuvanti mamev sarvabhuta-hite ratah)."
3. C-II: This is Verse 12.6, describing the path of devotion to the Personal God: "But those who renounce all actions in Me and regard Me as the Supreme... and meditate on Me with single-minded yoga (ananyenaiv yogena mam dhyayanta upasate)."
4. D-III: This is Verse 12.7, giving the Lord's promise to those devotees: "For them (Tesham-aham), I become the swift deliverer from the ocean of birth and death, for their minds are fixed on Me (bhavami nachirat-partha mayy-aveshita-chetasam)."
Step 3: Synthesis:
The pairs are: A-IV, B-I, C-II, D-III. This matches the exact sequence of the 12th chapter's foundational verses.
Step 4: Final Answer:
The correct matching sequence is (1).
