What is the correct JavaScript syntax to change the content of the HTML element below?<p id="demo">This is a demonstration.</p>{$a->questionintifier} Yanıta.document.getElementByName("p").innerHTML = "Hello World!";b.#demo.innerHTML = "Hello World!";c.document.getElement("p").innerHTML = "Hello World!";d.document.getElementById("demo").innerHTML = "Hello World!";

The correct syntax to change the content of the HTML element in JavaScript is:

d. document.getElementById("demo").innerHTML = "Hello World!";

Here's why:

• document.getElementById("demo") is used to select the HTML element with the id "demo".
• .innerHTML is used to get or set the HTML content of an element.
• "Hello World!" is the new content you want to set for the element.

So, the whole line of code is telling the browser to find the HTML element with the id "demo" and change its HTML content to "Hello World!".

The correct syntax to change the content of the HTML element in JavaScript is:

d. document.getElementById("demo").innerHTML = "Hello World!";

Here's the step by step explanation:

1. document.getElementById("demo"): This line of code selects the HTML element with the id "demo". In this case, it's the paragraph <p> element.

2. .innerHTML = "Hello World!";: This line of code changes the content (innerHTML) of the selected HTML element to "Hello World!".

So, when these two parts are combined, the entire line of code changes the content of the paragraph with the id "demo" to "Hello World!".
