The correct answer is: provisional.
Interim relief is a temporary measure that is taken until a final decision is made in a legal case. It is often used to protect the rights of one party while the case is being heard. In the context of the question, the workers are asking for provisional relief because they are worried that they will not be able to survive without it while the case is being heard.
The other options are not correct because they do not accurately describe the nature of interim relief. Immediate relief would be relief that is given immediately, without any delay. Extra relief would be relief that is given in addition to the relief that is already being given. Urgent relief would be relief that is given because it is needed very quickly.
I hope this explanation is helpful. Please let me know if you have any other questions.
