History

Hi Shivani,
You can take the following subjects according to the career you will be opting in future:
Journalism and Mass Communication, if you want a career in print media.
Political Science, if you are in for government job exams after completing graduation. It also helps in creating a general political awareness about your country and its international relationships with other states.
Philosophy, this subject may seem a bit unconventional but is a good choice if you are thinking about pursuing academia.
History is a nice subject with lots of interesting things and stories. Not so beneficial from the career perspective but you can take it if you don't like the other subjects and are looking for something easy and interesting to study.
Economics, Hell no, don't take it. I insist. I am not saying it is not useful or interesting. But it will eat up a lot of your time if you are a mediocre student as you cannot pass it by studying for one night like the above subjects. You need your time for honours, right? So don't go for it.
Regional language, or Hindi, you can go for it if you are fond of indigenous literature too. Can be helpful for your major course also.
Others, there are many other subjects which vary from college to college. You may choose them also. But whatever you choose, choose wisely, after discussing with your seniors who are experienced.
Best of luck.
Regards.
