Good to hear back from you!!
I guess this mail is before we have a telephonic conversation on saturday.
You can take up management at undergraduate level if you wish to do so. And if you are very decided that you want to get into HR or market research then certainly it makes sense that you take up management
If you wish to take up journalism then certainly you will have to opt for mass communication at undergraduate level which will expose you to fields like public relations, journalism, advertising etc. And then going through this you can choose any one at the graduation level.
Hope this helps.
