Answer 2

True or false in statements A, B and C.

Explanation:

• To decide whether statements A, B and C are true or false need to know that $p\rightarrow q \cong \sim p\vee q$.
• If p is true and q is true then $p\rightarrow q$ will be true.
• If p is true and q is false then $p\rightarrow q$ will be false.
• If p is true and q is false then $p\rightarrow q$ will be false.
• If p is false and q is false then $p\rightarrow q$ will be true.
• According to question, In statement A, p is false and q is false so, $p\rightarrow q$ is true.  
• In statement B, p is true and q is false therefore, $p\rightarrow q$ is false.
• In statement C, p is false and q is false therefore, $p\rightarrow q$ is true.

So, statement A and C is true and statement C is false.
