New avenues
Earlier, the profession of practicing law was limited to criminal and civil litigation. But now, the opportunities available for graduates from any of the top Law Schools are phenomenal. After the liberalization of India's economy, there is a huge demand for highly skilled lawyers who are adept in the areas of mergers and acquisitions, banking and finance, infrastructure contracts, debt restructuring, FEMA regulations, IPRs, corporate governance, private equity deals, WTO law etc. Law firms, both international as well as domestic, regularly recruit such lawyers in large numbers. Same is the case with big companies like TATA, Reliance, Infosys, Wipro, TCS, ICICI Bank, etc.
Students who do not like joining business law can find greener pastures in the environment or Human Rights in reputed organizations like CSE, ICRC, UNHCR, etc. For LLM students from premier Law schools, Business Laws and IP Laws are the branches, which offer excellent career opportunities.
Most of the magic circle and silver circle law firms like Clifford Chance, Allen & Overy, Herbert Smith, Simmons, etc. visit Indian campuses to recruit students for their various offices across the globe. Almost all the Indian law firms like Luthra and Luthra, Amarchand Mangaldas, AZB Partners, Nishith Desai Associates have also begun recruiting from the Law Schools.

Dear Ramu,
M.Com will be a continuation of your subject of graduation. It will give you further knowledge in the field of Accountancy or any other special subject you opt for. However, MBA is a quite practical subject with regards to exposure into the management domain. On completion of M.com you shall get a job into the field of of Accountancy or Taxation. Whereas, MBA shall start your rewarding career into the field of management. It will teach you all the skills required to handle day to day working of an organization, people management is a core part into it.
Studying LLB shall give you a wide scope of job as well as your own private practice. It will give you a vast knowledge of law of India. So it is absolutely different from M.com and MBA. It completely depends on your area of interest as to what you want to pursue.
I hope this would suffice. All the best and God bless you.
