Hello Vasu 

You can opt cs ; Mechanical; civil; production; IT .

In cs and it ; you need to learn coding and softwares which is all different from  physics chemistry and maths .

In mechanical and civil and production; there is only need of basic concepts of physics and after that it is mathematics. 

You can go with ece allso ; because what you have learnt till now only basic of this will be used and after that syllabus and all other things changes.

So good luck
