The water in response to the action force exerts a reaction force on the boat as per Newton's third law of motion. This reaction force pushes the boat in forward direction. b) When a bird flies, it pushes its wings in downward and backward direction. ... This force helps them to fly in the air.Because of the Momentum Conservation Law, sum of momentum of all objects participating in the action should be the same

During the rowing of a boat,the batsman pushes the water backward with oars.The water exerts an equal and opposite push on boat which makes the boat move forward.Harder the boatman pushes back the water with oars,greater is the reaction force exerted by water and faster the boat moves.
b)When a man jumps out of a boat to the bank of the river,the boat moves backward away from him.
To step out boat,the man presses the boat with his foo in backward direction(action).The boat exerts an equal force on man in forward direction(reaction)
c)When a boatman wants to take away from bank of river,he sits in the boat and pushes the river bank with oar:When boatman exerts a force of action on the bank,the bank exerts an equal and opposite force of reaction on the boat.So boat move away from bank.
