Here are codes that are placed in the different parts of the HTML. Ever variation will run no matter where the script tag is placed.
1.
<html>
<head>
<title>Foo</title>
<script type="text/javascript">
alert("hello world");
</script>
</head>
<body>
</body>
</html>
2.
<html>
<head>
<title>Foo</title>
</head>
<body>
<script type="text/javascript">
alert("hello world");
</script>
</body>
</html>
3.
<html>
<head>
<title>Foo</title>
</head>
<body>
</body>
<script type="text/javascript">
alert("hello world");
</script>
</html>
If you try out all these 3 variations where the script tags are placed in different parts of the HTML, you'll see that the alert() call will still run; regardless of their position in the HTML document.
So I think the answer to your question is:
C. Both of the above
Since there is no choice that says "Anywhere within the html document"

It is a good idea to place scripts at the bottom of the element. This can improve page load, because HTML display is not blocked by scripts loading.

我选择了上面的“C”，因为“脚本”可以放在 和 </body> 以及 <head> 和 </head> 之间的任何位置。在这种情况下，最合乎逻辑的答案是“C”
