(a)
Upward acceleration just causes the acceleration due to gravity increases by some value, but since the term of ' $g$ ' gets cancelled out in the buoyancy equation.
Volume immersed $\times \rho_w \times g=$ Total volume $\times \rho_{\text {gabe }} \times g$
So, increasing it will not have any effect on the immersed volume.
