Q 5 - What is the output of following program?

IDENTIFICATION DIVISION.
PROGRAM-ID. HELLO.

DATA DIVISION.
   WORKING-STORAGE SECTION.
   01 WS-DESCRIPTION.
   05 WS-DATE1 VALUE '20140831'.
   10 WS-YEAR PIC X(4).
   10 WS-MONTH PIC X(2).
   10 WS-DATE PIC X(2).
   05 WS-DATE2 REDEFINES WS-DATE1 PIC 9(8).

PROCEDURE DIVISION.
   DISPLAY WS-DATE2.

STOP RUN.

A - 00000000

B - 20140831

C - Compilation error

D - Run time error
