it depends if it ask about only acceleration of block m1 then it will increase if it ask acc due to gravity then it decrease for M2
a = g*(m2-m1 sin(alpha)/(m2+m1).
a for block m1 = sin(alpha) directly
for m2 g is inversely of sin (alpha)

As we know that a = g*(m2-m1 sin(alpha)/(m2+m1).

As alpha value will increase putting the value of alpha in in numerator the value of acceleration will decrease

think the option should be "A", u can derive the relation and check by substituting the value of alpha
