The question asks in which book by Hafeez Jalandhari is Pakistan's national anthem included. Hafeez Jalandhari is the revered poet who penned the lyrics for Pakistan's national anthem, known as 'Qaumi Tarana'.
The correct answer is C: چراغ سحر (Chiragh-e-Sahar). 'Chiragh-e-Sahar' is Hafeez Jalandhari's most celebrated and comprehensive collection of poetry. It compiles a significant portion of his poetic works, and it is within this esteemed collection that the lyrics of Pakistan's national anthem are formally published and preserved. This book is a cornerstone of Urdu literature and a testament to Jalandhari's poetic legacy.
The other options, A: چراغ عصر (Chiragh-e-Asr) and B: روشن چراغ (Roshan Chiragh), are not the correct titles of the collection that houses the national anthem. While they might sound like plausible book titles, 'Chiragh-e-Sahar' is the specific and historically recognized work containing the national anthem. Therefore, knowing the exact title of his major poetic collection is crucial here.
