  • A.Melvil Deway
  • B.S.R. Ranganathan
  • C.C.A. Cutter
  • D.Hartley

Answer: D

The name associated with the measurement of information is Hartley.

Ralph Hartley of Bell Laboratories, in his 1928 paper Transmission of Information, proposed measuring information as the logarithm of the number of possible messages. The Hartley is still a unit of information, and his work was the direct forerunner of Claude Shannon's information theory of 1948.

The others belong to other parts of library science. Melvil Dewey devised the Dewey Decimal Classification, S.R. Ranganathan the Colon Classification and the Five Laws of Library Science, and C.A. Cutter the Rules for a Dictionary Catalog and the Expansive Classification.
