I________________ for my exam on Sunday afternoon.Seleccione una:a. am going to reviseb. am revisingc. will revise

All of the options can be correct depending on the context:

a. "am going to revise" - This is used when you have decided or planned to do something in the future.

b. "am revising" - This is used when you are currently doing something or you have already arranged or decided to do it.

c. "will revise" - This is used when you decide to do something at the time of speaking or in the future.

So, if you have already planned to revise for your exam on Sunday afternoon, you would use "am going to revise". If you are currently revising or have already arranged to do it, you would use "am revising". If you just decided to do it, you would use "will revise".
