You can go for Mba which is a asuperset and relevant couree after bba, since it is highly managerial and involved all your BBA skills. try to choose from top 30 institutions.

If you have any interest towards laws, policies, social justice and possess good reasoning and analytical skills, go for law i.e bba llb.
If you like to analyse or manage data, ppl, things ,resources etc and hv business skills go for bba+ mba.
There are many psychometric tests which assess your skills, personality, interests and abilities to guide you towards the cluster of careers.

An hons course at bachelor's level is actually a mini specialization whereas general degree will give you the idea of business administration and law both. If you wish to know the difference in what you will be studying in both, just compare the course structure of both for whichever university you wish to apply and then decide.
