Which sentence type gives direction or command and can end with a period or an exclamation mark?

• A. Imperative sentence
• B. Exclamatory sentence
• C. Interrogative sentence
• D. Declarative sentence

Answer: (A)

Giving a direction or command is about the imperative mood. An imperative sentence tells someone to do something, with the subject usually understood as "you" even if it's not spoken. It can end with a period when the command is straightforward, or with an exclamation mark to show urgency or stronger tone, as in “Close the door.” or “Finish your homework now!” An exclamatory sentence, by contrast, expresses strong feeling rather than directing action, and ends with an exclamation mark. An interrogative sentence asks a question and ends with a question mark, and a declarative sentence makes a statement and ends with a period.
