Solution

The correct option is A. 1/2.
Fraction of volume immersed in the liquid is given by,
$V_{i n} = ⟮ \frac{ρ}{σ} ⟯ V$
The fraction of volume immersed depends upon the densities of the block and liquid. So there will be no change in it if the system moves upward or downward with constant velocity or some acceleration.
