Colon Classification

Step 1: Recall the history of Colon Classification (CC). Colon Classification was devised by S.R. Ranganathan. The first edition of the book "Colon Classification" was published in 1933.

Step 2: Deduce the construction period. The publication in 1933 was the culmination of a long period of intellectual work, design, and construction of the schedules. Ranganathan conceived the basic idea around 1924 and worked intensively on developing the system throughout his time in England and upon his return to India.

Step 3: Evaluate the options. The period from 1925 to 1932 represents the primary years of development leading directly to the first publication. The other options are either too early, too late, or span an unnecessarily long period. The most accurate and focused timeframe for the construction of the first edition's schedules is 1925-1932.

Step 1: Recall the Facet Formula for Literature (O) in Colon Classification. The facet formula for the main class 'O' Literature is O[P], [P2], [P3], [P4]. Each [P] represents a facet.

Step 2: Identify what each facet represents in the 6th edition of CC.

Step 3: Arrange the facets according to the formula. The correct sequence is Language, Form, Author, Work. This corresponds to the letters (A), (B), (D), (C).
