As the motion is only in 1-Dimension so,There is no need for vecor sign. WE can assume as +se as vertical direction And -ve  as downwars Direction.
a(relative)= a1-a2
according to our convention vertical motion is +ve and downward motion is -ve.
So. a1=+g
       a2=-g
Hence ,
            a(relative) = a1-a2
                                     =(+g)-(-g)
                                      =g-g
                                      =0.

Dear Taniya, no need to fret. This is a very simple question used for confusing the students. Since the acceleration of both the bodies will be g downwards, therefore their relative acceleration will be zero.
Taking upward direction to be positive and ground as refrence, we have:
  Acceleration of 1st body = a1 = -g
  Acceleration of 2nd body = a2 = -g
 \therefore Acceleration of 1st body wrt 2nd is given by:
              a12 = a1 – a2 = -g – (-g) = 0
