To add CSS to an entire HTML document using an internal style sheet, you can use the <style> element within the <head> section of your HTML document. The correct method is indeed to use the internal style sheet, which involves writing CSS rules inside the <style> tags.

Here's an example of how to do this:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Your Page Title</title>
    <style>
        /* CSS rules go here */
        body {
            font-family: Arial, sans-serif;
            background-color: #f0f0f0;
            color: #333;
        }
        h1 {
            color: #4CAF50;
        }
        p {
            font-size: 16px;
        }
    </style>
</head>
<body>
    <h1>Welcome to My Page</h1>
    <p>This is a paragraph of text on my web page.</p>
</body>
</html>

In this example, the CSS rules defined inside the <style> tags will apply to the entire document.

Regarding the options you provided:

Option C: "by importing part of a style sheet" - This typically refers to using @import to include an external stylesheet, which is not what internal style sheets are about.
Option B: "by placing the style attribute within another HTML element" - This refers to inline styling, which is different from an internal style sheet.

Thus, to summarize, the correct method for adding CSS to an entire HTML document using an internal style sheet is to place CSS rules within the <style> tags in the <head> section of the HTML document.
