Step 1: Identify the establishment year for each item:\[\begin{array}{rl} \bullet & \text{(A) Imperial Library: Established in 1903.} \\ \bullet & \text{(B) National Library of India: Established in 1948.} \\ \bullet & \text{(C) Delivery of Books Act: Established in 1954.} \\ \bullet & \text{(D) NAPLIS (National Policy on Library and Information System): Established in 1985.} \\ \end{array}\]
Step 2: Order the items chronologically based on their establishment years. The correct sequence is 1903, 1948, 1954, and 1985.
Step 3: Associate each year with its corresponding item. The chronological order of the items is Imperial Library (A), National Library of India (B), Delivery of Books Act (C), and NAPLIS (D), resulting in the sequence (A), (B), (C), (D).
