D Correct answer
Explanation

BOOLEAN is not a standard COBOL datatype. Traditional COBOL uses PICTURE clauses to define data formats like ALPHABETIC (A), ALPHANUMERIC (X), and NUMERIC (9 or S9). While modern COBOL implementations may support boolean-like conditions, BOOLEAN as an explicit datatype is not part of standard COBOL. The question asks which datatype is NOT used in COBOL - BOOLEAN is the correct answer.
