In the figure shown if friction coefficient of block \( 1 \mathrm{~kg} \) and \( 2 \mathrm{~kg} \) with inclined plane is \( \mu_{1}=0.5 \) and \( \mu_{2}=0.4 \) respectively, then
(a) Both block will move together
(b) Both block will move separately
(c) There is a non zero contact force between two blocks
(d) None of these
