hey abhishek
you can chose anyone of them. you can chose physics chemistry biology after your 10th or you can do ag diploma as both are equivalent .if you chose pcb then you can give entrance exams of some goood collleges . ag diploma is not that tough but yes chosing in between pcb or diploma also depends upon the collegs you are looking for
best wishes
