Explanation
The alt attribute is required on <img> elements for HTML5 validation because it provides alternative text that describes the image when it cannot be displayed, and is essential for screen readers and accessibility compliance - HTML5 validators will flag its absence as an error.
The other options are all optional attributes: id is a global attribute used for targeting elements with CSS/JS but is never required; name is a legacy attribute largely replaced by id and not required on images; title provides supplemental tooltip text but is purely optional and not enforced by the HTML5 spec.
Memory tip: Think "alt = always" - the alt attribute must always be present on every <img> tag, even if its value is empty (alt="") for decorative images.
