Hello,

Comparatively cso has few chances however it is also in demand. But comparatively CSD and CSM are in high demand. By 2022 75% of jobs will be raised for data Science and Machine Learning. So lastly, if you are interested in those areas then you can go for it  else you can take CSO. Adding on,  all these courses are interrelated to each other. So even if you take one course. After completing the course, you can explore in other courses also. That means you can have chances of employment in all those 3 courses.
