Assuming a page with four paragraph tags, what is the correct code to change the content of the second paragraph?

The correct code to change the content of the second paragraph is indeed represented in the first choice. Using document.getElementsByTagName('p')[1].innerHTML = "What does the Fox say?" effectively targets the second paragraph element on the page.

Here's how it works:

1. The document.getElementsByTagName('p') method retrieves a live HTMLCollection of all paragraph elements (<p>) present in the document.

2. This collection is indexed, starting from 0, meaning the first paragraph is accessed with an index of 0, and the second paragraph is accessed with an index of 1.

3. By appending [1], we specifically select the second paragraph.
