Statement analysis:

a) "Get me a glass of milkshake."
This statement is a command or request, not a proposition. It is asking someone to perform an action.

b) "God bless you!"
This statement is an expression of well-wishing or a blessing. It is not a proposition because it does not express a truth value.

c) "What is the time now?"
This statement is a question asking for information. It is not a proposition because it does not make a claim or express a truth value.

d) "The only odd prime number is 2."
This statement is a proposition because it makes a claim that can be evaluated as true or false. It states that there is only one odd prime number, which is 2. This can be verified and proven to be true or false based on mathematical knowledge.

Explanation:

A proposition is a statement that can be evaluated as true or false. It must express a complete thought and have a clear truth value. In this case, the statement "The only odd prime number is 2" is a proposition because it makes a claim about the nature of prime numbers. It states that among all prime numbers, there is only one that is odd, which is 2. This claim can be evaluated and proven to be either true or false based on mathematical knowledge and definitions.

In contrast, the other options do not meet the criteria of a proposition. Option a) is a command or request, option b) is an expression of well-wishing, and option c) is a question asking for information. These statements do not make claims that can be evaluated as true or false.

Therefore, the correct answer is option d) "The only odd prime number is 2" because it is the only statement that qualifies as a proposition.
