Hi Vikas,
If you're going to apply for improvey in only one subject then it is quite obvious fact that the marksfor rest three will remain same as they were before. So yes, you can use that improvement marksheet for that subject.
If the result for improvement is delayed, then you can submit the marksheet later also as DU has always specified a particular time limit for submission of delayed result related documents.

Hello Nishant,
Hope you are doing well.
Every course is given with some extra time limit. For example, in case of engineering you have 7 years to complete this 4 year graduation program.
Like this, some extra years are also be given for your program you can ask your college authorities.
Good luck
