The answer is: D
Explanation
The correct option is D: None of these.
According to the Indian Evidence Act, 1872, Section 3 defines "document" as including any matter expressed or described upon any substance by means of letters, figures, or marks, or by more than one of those means, intended to be used, or which may be used, for the purpose of recording that matter. The definition is quite broad and encompasses various forms of records and representations.
A: An inscription on a metal plate or stone - This falls under the definition of a document as it involves matter expressed upon a substance.
B: A map or plan - This also falls under the definition of a document as it represents information in a visual form, expressing matter through marks.
C: A caricature - This can be considered a document as well, as it represents a form of expression through figures and marks.
Therefore, all the options (A, B, and C) are considered documents under the Indian Evidence Act, and the correct answer is D: None of these.
