What bug tracking software do you use?
Free/Cheap Task/Bug Management software
I am working as a Jr. Software Tester (Manual testing) in a firm. Here, we dont have a bug-tracker to report the errors in the application. So, I need a tool preferably open-source for bug-tracing. It should be a best one.

If you need something fairly simple, free and open-source I'd say use TRAC. In our company we use both Trac and Fogbugz. The latter is not free but it works really well.
Please see these previous SO questions:

I keep hearing there are tons of bug trackers, but not so many build in .net
What is your bug/task tracking tool?
Having Trouble Finding The Right Bug Tracker Software
We are using phpBugTracker . It is not as powerful as Trac or Bugzilla because you cannot integrate it to any IDE which is a great feature. But it works. It is light weight and very easy to install.
I use Bugzilla. It's open source.
(I don't know of any way to decide what would be "best" for you)
