What does robinson make from the iron tree? a. a spear c. a canoe b. a fishing pole d. a shovel - robinson crusoe” by daniel defoe.

Robinson made D. a shovel from the iron tree.
He knew that this type of a tree existed in Brazil and was hoping it would be somewhere around the island too. And he was right - thus he used it to make a shovel which drastically helped him plant his food and make his house. 

I would say in between ✨✨✨✨✨✨
