 Fifth option:  
 
Step-by-step explanation:
 By definition, a perfect square trinomial can be obtained by squaring binomials.
 Then:
 
 Knowing this, to obtain a perfect square trinomial, the binomials that you multiply must be equals.
 Therefore, the products result in a perfect square trinomial are:
 
 
 
 
 
        
                    
             
        
        
        
From the chord theorem we have:
