Answer:
option 3
Explanation:
Draw yourself the free body diagram of figure.
friction force due to m2 and m3 = μN + μN = 2 μmg;N [m1 = m2 = m]
∵Net accelration is downward
∴ m1g - 2 μmg = (m1 + m2 + m3)a
=> mg(1 - 2 μ) = 3ma (a is accelration of m1,m2 and m3 block)
=> a = g(1 - 2 μ)/3

Can u draw a diagram of this solution
i can draw, but i can't give
hope you understand!
hope you understand!
you have to only mention the gravitational force(mg) in downward direction , friction force in opposite direction and acceleration of block
Ok np
Thanku
