Which one of the following propositional logic formulas is TRUE when exactly two of p, q, and r are TRUE?

Option A. ((p ↔q) ∧ r) ∨(p ∧ q ∧∼ r)
Option B. (∼(p ↔ q) ∧r) ∨ (p ∧q ∧ ∼r)
Option C. ((p →q) ∧ r) ∨(p ∧ q ∧∼ r)
Option D. both a and b
True Answer B

Explanation :

 propositional logic formulas is TRUE when exactly two of p,q and r are TRUE means possibilities are pq or qr or pr to be TRUE  

 

option A)  
  ((p↔q)∧r)∨(p∧q∧∼r) 
=((T↔T)∧r)∨(T∧T∧∼r) ( take p=T and q=T) 
=((T)∧r)∨(T∧∼r) 
=(r)∨(∼r) 
=T  
It doesn't depend upon the value of r, so, if the value of r is T then it also to be T so the condition exactly 2 are T is false. Hence option A is FALSE.

option B) 
  (∼(p↔q)∧r)∨(p∧q∧∼r) 
=(∼(T↔T)∧r)∨(T∧T∧∼r)  ( take p=T and q=T)  
=(∼(T)∧r)∨(T∧∼r) 
=(F∧r)∨(T∧∼r) 
=(F)∨(∼r) 
=∼r  
so if r=F then this is T so condition exactly 2 are T is true

 (∼(p↔q)∧r)∨(p∧q∧∼r) 
=(∼(T↔q)∧T)∨(T∧q∧∼T)  ( take p=T and r=T)  
=(∼(q)∧T)∨(F) 
=∼(q)∨(F) 
=∼q 
so if q=F then this is T so condition exactly 2 are T is true

(∼(p↔q)∧r)∨(p∧q∧∼r) 
=(∼(p↔T)∧T)∨(p∧T∧∼T)  ( take q=T and r=T)  
=(∼(p)∧T)∨(F) 
=∼(p)∨(F) 
=∼p 
so if p=F then this is T so condition exactly 2 are T is true

Hence option B is CORRECT.

option C) 
   ((p→q)∧r)∨(p∧q∧∼r) 
=((T→T)∧r)∨(T∧T∧∼r) ( take p=T and q=T)  
=((T)∧r)∨(T∧∼r) 
=(r)∨(∼r) 
=T 
It doesnt depend upon value of r , so , if value of r is T then it also to be T so the condition exactly 2 are T is false . Hence option C is FALSE.

option D) 
    (∼(p↔q)∧r)∧(p∧q∧∼r) 
=(∼(T↔T)∧r)∧(T∧T∧∼r)  ( take q=T and r=T)  
=(∼(T)∧r)∧(T∧∼r)   
=(F∧r)∧(T∧∼r)   
=F∧(∼r) 
=F   
It doesnt depend upon value of r , so , if value of r is F then it also to be F so the condition exactly 2 are T is false . Hence option D is FALSE.

Which one of the following propositional logic formulas is TRUE when exactly two of p, q, and r are TRUE?
