Solution

$(A)$ Boat get attracted towards the magnet i.e Boat is made of magnetic material. That is why it is attracted towards magnet.
$(B)$ If Boat is not affected by magnet that means Boat is made of non-magnetic material.
$(C)$ Boat moves away from magnet when north pole is brought near its head i.e Boat had north pole towards its head ("Like pole repel each other')
$(D)$ Boat moves away from the magnet when north pole is brought near its head i.e head is made of south pole and it repel north pole.
$(E)$ Boat float without changing its direction i.e. Boat has small fixed magnet along its length.
