The correct answer from the following logically equivalent statement is option 3) Neither is a tautology. Neither statement (a) nor statement (b) is a tautology.
A tautology is a statement that is always true regardless of the truth values of its variables. To determine if statements (a) and (b) are tautologies, we can create truth tables for each statement and analyze their truth values.
For statement (a):
(p -> q) v (p -> ~q)
| p | q | ~q | (p -> q) | (p -> ~q) | (p -> q) v (p -> ~q) |
|:---:|:---:|:---:|:-------:|:--------:|:--------------------:|
| T | T | F | T | F | T |
| T | F | T | F | T | T |
| F | T | F | T | T | T |
| F | F | T | T | T | T |
As we can see from the truth table, the statement (a) evaluates to true for all possible combinations of truth values, but it is not true for every possible case. Therefore, statement (a) is not a tautology.
For statement (b):
(~p -> q) v (p -> q)
| p | q | ~p | ~p -> q | p -> q | (~p -> q) v (p -> q) |
|:---:|:---:|:---:|:------:|:-----:|:--------------------:|
| T | T | F | T | T | T |
| T | F | F | T | F | T |
| F | T | T | T | T | T |
| F | F | T | F | T | T |
Similarly, the truth table for statement (b) shows that it evaluates to true for all possible combinations of truth values, but it is not true for every possible case. Hence, statement (b) is also not a tautology.
Therefore, the correct answer is option 3) Neither is a tautology.
