You are pursuing CA that itself is a well renowed degree that will fetch you a handsome career but in todays world since the competition so so high its better to do something extra .
1. The best option after CA is to prepare for CAT to get admission in Tier 1 B schools . i am suggesting that because from whichever field you start your career after spending so many years as a doer you evevtually upgraded the management level where u only have to manage the other people in the organisation . so its better to get the MBA degree and start your career as a manager itself if you want the join the big league . If you do not get admission in the big MBA schools than its better not to pursue the course as you might be knowing the fact that lacs of MBA are coming every year which is of no worth as your knowledge gained at the big B school matter for your growth not your degree . and after preparing for CAT you can also give various Goverment job exams
2. but if u so not want to go for MBA then your choice should be dependant to your need that means in whatever field you want to go or get job you should choose the course that will help you in your growth . i.e. Domail focussed course
Doing the course only for the purpose of getting a degree weighs nothing in the eyes of employer unless your knowledge is usefull in your daily working
