Let $T=$ tension in rope. Force $T$ acts on both. The limiting force of friction is larger for the block than for the man. each body will move when $T$ exceeds the force of friction. limiting friction on man $<$ limiting friction on block
hence when $T$ exceeds limiting friction of man then man will start moving but block can't
but if $T$ exceeds the limiting friction of block then block will also start moving but with acceleration less than man
thus,
Option $\mathrm{A}, \mathrm{B}, \mathrm{C}$ are correct
