To pursue my career of Astrophysics after Engineering

Hello Sir\Mam,
I'm Bhagyalaxmi and I'm 14 years old. For my future I want to go for a Scientist/Engineer ‘SC’ job in ISRO. So my question is which can be the best Engineering branch I can go for the job as a Scientist.
My parents want me to complete my B.tech after clearing JEE. And after Engineering I want to become a scientist. So please recommend me the best branch of engineering I can choose for. This is the only way I can complete my parent's dreams and my dream to work as a Scientist for our country in ISRO 😀
