Hello Maheeka,
Decision of course depends on your interest.If you want to specialise in various branches of company law then you can opt for BBA LLB course This would help you understand corporate structure in depth.
The LLB course is  in two formats  - 5-year integrated LLB course for Class 12 pass-outs and a 3-year LLB course for graduates of any stream. The advantage is that those who miss the chance after Class 12 will have an opportunity to study law after graduation.
Both BBA & BBA LLB are same.
Secondly,
BBA and MBA will help you to understand corporate world invarious aspects.MBA will help you to unleash various department of organisation.Your work won't be limited to company law.So it depend on interest and where you want to see yourself in 10-15 years.
Hope I cleared your doubt.All the best for future!!

Ya B.A.LLB or LLM is best for your.
