Explanation:

This HTML code defines a webpage with a form and a dropdown menu.
The form is set to submit data using the POST method to a specified URL.
The dropdown menu allows users to select one option from the provided choices.
Each option in the dropdown menu represents an animal.
The size attribute is added to the <select> tag, specifying the number of visible options in the dropdown menu.
In this case, the size is set to "2", so only two options will be visible at a time without the need for scrolling.
This attribute provides a way to control the appearance and behavior of the dropdown menu based on the number of options to be displayed.
