Hello Ashish,
For admission in BA hons journalism you should score a minimum of 45% marks or more in English and a combination of other three elective subjects form the list A and List B and mass media given in the Bulletin of information for admission in under graduate courses.
If you include other subjects that are not mentioned in the two lists then a deduction of 2.5% per subject is made from the aggregate.
You can download the Bulletin from the official website of Delhi university.
I hope this helps.
All the best for the future!!
