Hi Falak,
No. I am really sorry to tell you that you cannot apply for a Bachelor degree after failing in class 12th. You can take admission in Diploma programs based on your 10th mark-sheets but I will advice you to reappear in class 12th to have a safe and secure future.
All the best.

Distance education (Degree) approved by DEC, UGC/ AICTE is valid for both government and Private job at all level. That is technical view for the legality issue for distance education.
However,
Job to Job and case to case, more than a degree, criterion for the position outwit full-time education over distance education.

In case you have failed then you have to reappear before you plan to change your stream.
