Which of the following attributes of the img tag is required for strict XHTML compliance while
embedding images in a Web page?
A.
alt
B.
src
C.
id
D.
xml:lang
Explanation:
The <img> tag is used to embed an image in an HTML page. Images are linked to HTML pages and
are not technically inserted into an HTML page. The <img> tag creates a holding space for the
referenced image. The <img> tag has two required attributes: src and alt. The <img> tag is supported
in all major browsers. It is not required to put an end tag in HTML, but in XHTML, the <img> tag must
be properly closed. The alt tag is acceptable for HTML, but it is required for XHTML. For example:
<img src=”image1.gif” alt=”Image is loading” />
Answer B is incorrect. This attribute specifies the URL of an image.
Answer D is incorrect. In XHTML documents, this attribute specifies a language code for the content
in an element.
Answer C is incorrect. This attribute specifies a unique id for an element.
