If you are interested in finance-related subjects you can choose Financial Services & Capital Market or Risk Management as an elective. But as per my opinion, Financial Market is a better option as this subject is scoring also. Some part of the syllabus gets covered in SFM only which makes it easy to understand and prepare for exams. For Financial Services & Capital Market, you can go for Aaditya Jain sir classes. He is a master in the finance field.
