Sentences in English can be classified into different types based on their purpose.
A declarative sentence states a fact or opinion and ends with a full stop.
An interrogative sentence asks a question and ends with a question mark.
An exclamatory sentence expresses strong emotion or surprise and ends with an exclamation mark.
An imperative sentence is used to give an order, command, make a request, or offer advice.
For example: “Sit down.” (command), “Please pass the salt.” (request), “Take care of your health.” (advice).
Therefore, the correct answer is Imperative.
