Correct option is B
Given: Canoe, Dinghy, Igloo, Raft, Yacht
Logic: Canoe, Dinghy, Raft, and Yacht are all types of boats or watercraft used for navigation on water.
Igloo is a type of shelter/house made of ice, not related to boats or water transport.
So, Igloo is the odd one out.
Thus, the correct answer is (b).
