A Boat Has an Initial Velocity of 2 M/s in the Y

A boat has an initial velocity of 2 m/s in the y direction on a stream which is moving in the x direction at 1 m/s.The boat is accelerating in its direction of motion at 1 m/s².What is the acceleration of the boat (in m/s²) relative to the water?

B) 2 $\hat { \mathbf { i } }$
C) 3 $\hat { \mathbf { i } }$ + $\tilde{j}$
D) 3 $\hat { \mathbf { i } }$ - $\tilde{j}$
E) 1 $\tilde{j}$
