Dear,

Option between these two depends purely on the subjects you are studying in B.sc. If you are pursuing Bsc from it or Computer science related field then you can opt for MCA or M.sc computer science. You can get lateral admisiion in MCA if you have done Bsc computer science in some colleges. MCA is not a good choice because if you are not familiar with computer science in past.

On the other hand you can opt for MBA after B.sc from any field. If you are interested in management they absolutely go for MBA and also MBA is great carrier option for master or post graduation . ,MBA has more job opportunities

both the fields are good. You can opt for anyone based on your interest. If you are deserving you will get good jobs from both the fields.

You should consider where your interest lies and where you can portray your skills in a better manner to make a good decision.

Hope it Helps!
