What are the components of acceleration

Question

For a steady two-dimensional flow, the scalar components of the velocity field are V_x = -2x, v_y = 2y,  v_z = 0. What are the components of acceleration?  

(a) a_y = 0,  a_y = 0         (b) a_x = 4x, a_y = 0

(c) a_x = 0, a_y = 4y        (d)  a_x = 4x,  a_y = 4y
