B Correct answer
Explanation

In COBOL, the UNSTRING statement requires the sending field to be a data identifier (variable name), not a literal. The syntax UNSTRING "ABC" is invalid because literals cannot be used directly. Option A is incorrect because DELIMITED BY is optional for simple unstringing. Options C and D are incorrect because the statement will not execute due to the syntax error.
