It totally depends on your interest. There is no specialization that does not allow or is not suitable for girls. However statistics suggest maximum number of girls in HR and Marketing.

Hello 

For the girls the two best option in MBA is MBA(HR) and MBA(Finance)

These two branches are the best siisui for the girls doing MBA 

Marketing job are also one of the best options but it's more of struggling on the field and the above two mentioned are more of desk jobs.

Thank you
