Step 1:I'll solve this step by step, focusing on Boolean expressions:
Step 2:: Understand Boolean Expressions
A Boolean expression is an expression that evaluates to either True or False. It involves logical comparisons or logical values.
Step 3:: Analyze Option A - True
\text{True}$$ is a literal Boolean value.
This is a valid Boolean expression.
Step 4:: Analyze Option B - 3 == 4
This is a comparison operator (==) that checks equality. It will evaluate to False, making it a Boolean expression.
Step 5:: Analyze Option C - 3 + 4
This is an arithmetic operation that results in 7, not a Boolean expression. It does not evaluate to True or False.
Step 6:: Analyze Option D - 3 + 4 == 7
This is a comparison that checks if 3 + 4 equals 7. It will evaluate to True, making it a Boolean expression.
Step 7:: Analyze Option E - False
\text{False}$$ is a literal Boolean value.
This is a valid Boolean expression.
Final Answer
Option C is not a Boolean expression.
