I am a boy of 14 .i am a student of 9 standard

That's great to hear! As a student in the 9th standard, you're likely to have many questions related to your studies or other aspects of your life. Remember that asking questions is an essential part of the learning process, and seeking answers is a way to expand your knowledge and enhance your understanding.

If you have any specific questions or topics you would like to know more about, feel free to ask, and I'll do my best to provide you with a helpful explanation.
