A Correct answer
Explanation

COMP-1 (single-precision floating point) in COBOL does not accept a PIC (PICTURE) clause because it uses internal binary representation, not the character-based format that PIC defines. COMP, COMP-3, and DISPLAY can all have PIC clauses to define their data layout. COMP-1 is pre-defined as a 4-byte floating-point format.
