Which of the two doctype declarations in the preceding post should be used?

How does one properly and correctly show markup within an entry so that it can be discussed? I’m told that the word, ”I’m” requires a special character for the apostrophe.

Here is the word without the special character: I’m

Here is the word with the special character – & rsquo;: I’m

Here is the word with the special character – & #8217;: I’m

I had to put a space after the ampersand to actually show the code. Why? What’s the better way? I want to be able to show the code I’m using and ask questions about it. Help!
