Correct option is A
No, you cannot appear for the SSC CGL exam right after completing 12th grade. To be eligible for SSC CGL, a candidate must have a Bachelor’s degree from a recognized university or institution. It doesn’t matter which stream you are from, but graduation is a must. If you are a 12th pass student, you can start preparing early to build a strong foundation. Meanwhile, focus on completing your degree. Once you graduate, you can apply. There are other exams like SSC CHSL for 12th pass students, but SSC CGL is strictly for graduates only.
