<head> and <html> tag mandatory for being valid HTML-file?

In one of the HTML challenge question it was asked whether which tags are needed for being a valid HTML file. The accepted answers were <html> and <head>. I think this is not quite correct. Because since HTML5 it is allowed to omit the <head> and <html> (and also the <body>) tags.
