Riddle: what kind of tree can you carry in your hand because its name is also a part of the human body?

Introduction / Context:
This classic English riddle plays on the fact that the same word can describe both a tree and a part of the human body. Rather than asking about botany or biology directly, it checks whether the learner can notice that some everyday words have more than one meaning. Such wordplay riddles are very common in reasoning sections of competitive exams and help improve vocabulary and lateral thinking.

Given Data / Assumptions:

• We are asked: what kind of tree can you carry in your hand.
• The riddle is about the name of the tree, not literally picking up a full sized tree.
• The answer must be a real tree name.
• The tree name should also relate naturally to something that can be on or in your hand.
• Exactly one option is the standard riddle answer.

Concept / Approach:
The key idea is that the word palm has two meanings. It can mean the inner surface of the human hand, and it is also the name of a common tropical tree. So you can say that you can carry a palm tree in your hand because you always carry your own palm with you. The question is therefore using a pun based on this double meaning. We simply look for a tree whose name is also closely connected to part of the hand, which immediately suggests palm tree.

Step-by-Step Solution:
Notice that literally carrying a banyan, mango or coconut tree in your hand is impossible because full trees are very large and heavy. Think about wordplay: does any tree name sound like or exactly match a part of the hand. The inside of your hand is called your palm. There is also a well known tree called a palm tree. Therefore, the only tree you can carry in your hand in the sense of wordplay is a palm tree.

Verification / Alternative check:
Check each option. Banyan, mango and coconut trees do not share their names with any part of the hand, arm or fingers. But palm tree contains the word palm, which is directly the part of the hand that touches objects when you hold them. The riddle does not require you to carry the entire tree physically; it only requires that the name of the tree can logically fit in or on your hand. This confirms that palm tree is the unique answer that fits the intended wordplay.

Why Other Options Are Wrong:
Banyan tree is massive and cannot be associated with the word for your hand. Mango and coconut are fruits and trees, but their names are not used for any part of the human body. They are included only as plausible sounding tree names to distract from the simple but clever connection between palm and palm tree. Since the riddle depends on the double meaning of palm, none of the other options satisfy the wordplay condition.

Common Pitfalls:
Learners sometimes interpret the question literally and try to imagine carrying a very small sapling of some tree in their hands, which misses the pun. Others may think too deeply about species of miniature decorative trees. In riddles like this, it is important to remember that many English words have more than one meaning. Always check whether a single word fits two roles at once, as palm does here, instead of only thinking physically or concretely.

Final Answer:
The tree you can carry in your hand is a palm tree, because you always carry your palm with you.
