مرزا غالب کے دیوان کی کتنی جلدیں ہیں؟

In Urdu poetry, a "Diwan" refers to a comprehensive collection of a single poet's ghazals and other poetic forms, typically arranged alphabetically by rhyme scheme. Mirza Ghalib's most celebrated and foundational work is his "دیوانِ غالب" (Diwan-e-Ghalib).

• Option D, 1, is the correct answer. Mirza Ghalib's primary and most famous collection of poetry, "دیوانِ غالب," is traditionally published as a single, complete volume. While various editions or commentaries exist, the core body of his collected works constitutes one unified Diwan.
• Options A, B, and C (2, 3, 4) are incorrect. Ghalib's collected poetic works are not divided into multiple volumes in the sense of separate parts of the same literary collection.
