Answer :
Answer:
The set \( P \) is defined as \( P = \{ x \mid x = 2 \} \).
This notation means \( P \) is the set of all elements \( x \) such that \( x \) equals \( 2 \).
- An **empty set** is a set with no elements. \( P \) is not empty because it contains at least one element (which is \( 2 \)).
- A **finite set** is a set that has a finite number of elements. \( P \) contains exactly one element (\( 2 \)), so it is finite.
- An **infinite set** is a set that has an infinite number of elements. \( P \) is not infinite because it only contains one specific element (\( 2 \)).
- A **singleton set** is a set with exactly one element. \( P \) is a singleton set because it contains exactly one element, which is \( 2 \).
Therefore, the correct answer is (D) singleton set.
