Can I study astrophysics if I have only studied Physics not Biology or Chemistry in my O levels? If yes then what job opportunities are there for it? And what other major can I do with it?
It's wiser to go for all sciences + maths as a subject for A-levels or GCSE's.Here in U.K to study astrophysics having A-levels in Physics and Maths is antagonistic.For higher rankings unis all the sciences are preferred.

As far as job opportunities, it of course depends on what degree you have.
If you get a bachelor's in astrophysics, then you have pretty much the same job opportunities as someone with a physics or math degree - most quantitative careers that aren't research/teaching focused. Some examples of people I know in astrophysics went on to be financial analysts, teachers (secondary school), government contractors (eg. working on satellite image data, the energy sector, etc.), software designers (depends on your background), medical physicists, etc.
I'm currently getting a PhD in astrophysics and the people I know who have left academia with a Masters degree have gotten similar jobs (usually government contractors, working at national labs, or in finance). If you want to have a serious research position (even outside of your field) or a permanent teaching position at a university you'll need a PhD.
