Add the correct punctuation mark from the given options.

This is a coconut tree _____

The correct answer is: Full stop (.)

A full stop (.) is chiefly used to end a sentence. It is mostly used at the end of declarative sentences and imperative sentences. A full stop marks a longer pause than a comma and a semicolon. Furthermore, it marks the end of a thought and the beginning of another sentence. 'This is a coconut tree.' Here full stop marks the end of a thought.
