Regarding CA final Elective paper

Hello everyone, I need some guidance to choose CA final elective paper.

I am interested in working with investment banking companies after CA Final.

I think, out of 6 papers Risk management, Financial services & Capital market and International taxation concepts (i.e., 6A, 6B and 6C) have equal importance in investment banking industry (please correct me if I'm wrong).

I am confused in choosing one from this 3 papers. So, I need some guidance from people working in investment banking industry and information regarding which specilization will be be preffered by investment banking companies.

Thank you.
