B. Expected clickthrough rate, landing page experience, and ad relevance.

Explanation:

Here’s an example of a good user experience based on an ad that is high quality and relevant. Let's say that you own a website that specializes in socks, and Sam, a customer, is looking for striped socks. Here’s how your ad (and high Quality Score keywords) connects Sam with what he wants.

When Sam searches Google for “men’s striped socks,” he sees your ad. (Your ad has “[striped socks]” as a keyword.)

Sam clicks the ad and lands right on your website’s “striped men’s socks” page. The page loads quickly and is easy for Sam to use.

Sam buys several pairs of striped socks.

That's what we consider a great user experience. Beyond a potentially higher Quality Score in most cases, relevant ads tend to earn more clicks, appear in a higher position, and bring you the most success
