Seems your friend is an Arts Students. I have 3 suggestions, based on the subjects she had chosen, as well as considering future career scope and prospects.

1. BA Economics

Economics has a huge scope today in India, and assuming the candidate is from West Bengal, since she has Bengali as one of the Subjects, West Bengal has a strong culture of Economics, with 2 Noble Laureates in Economics and excellent faculty at Colleges and Public Universities for Economics. After BA in Economics, you effectively can pursue a MBA, maybe go for a MA in Economics, become a Economist, take up Jobs with Finance, Taxation, Economic, Analytics or Commercial Firms, become a Teacher or Professor after PG/PhD or maybe pursue Government Services preparing for Examinations like WBCS, UPSC CSE, SBI PO, RBI Grade B, IBPS PO or Indian Economic Services Exam.

2. BCA

The IT and Software Sector somewhat generates strong Job prospects today. Incase she is interested or maybe inclined towards Computer Applications, she might pursue BCA. However BCA, she will require pursuing MCA from some of the Top NITs, Top Public Universities like JU, Etc. Or Good Private Institutions like IEM for strong career scope and placement prospects.

3. BA English

If she is interested in careers like Journalism, Marketing, HR, Media & Communication or maybe Professional Teaching, or plans to pursue Government Service Exams in Future, BA English is another Good Option.
