None of those are true necessarily.

Here is a counter-example which shows that:

, , 

We show that in this case:



is true by substituting:





Now we show that

 is true by substituting:





Then we show that

 is true by substituting:





And finally we show that

 is true by substituting:





Now look at the four choices:

choice (1)     

Substituting:   which is false

choice (2)   

Substituting:   which is false

choice (3)    

Substituting:  which is false

choice (4)

Substituting:  which is also false.

So you can tell your teacher that this is a bogus problem.
