Expert Answer:

qn.8 :-  Graph-A represents the acceleration of block as a function of t.   Acceleration ( g sinθ ) is constant throughout the motion
 
qn.9 :- Graph-E represent the displacement from starting point.   Displacement S is given by, S = u t - (1/2) g sinθ t2 ,
                   it is a quadratic function similar to equation of projectile motion.
 
qn.10 :- Graph-C represents the speed of block. speed v is given by,  v = ( u sinθ - g sinθ t ) , a linear function of t,
                    initially decreasing linearly and then increasing linearly while coming down
