Question

Mention the clause:
ones you have written all the answers, you can
handover the papers to the examiner​

Answer 1

Answer:

First of all, the spelling should be Once . It cannot be ones as per context. It is working as a conjunction.

( once you have written all the answers), > Subordinate clause / Adverbial clause denoting Time. you can handover the papers to the examiners. > Main Clause.
