When HTML is used to describe a Web page, which of the following is an appropriate
point to be noted?
a) HTML and browser specifications are standardized for each PC manufacturer.
Therefore, in order to display a Web page correctly, it is necessary to describe it for
each type of PC.
b) Even if the HTML description is the same, a Web page may be displayed differently
depending on the browser used. Therefore, when a Web page is described, it is
necessary to confirm how it is displayed by each browser.
c) HTML is standardized for each browser used. Therefore, in order to display a Web
page correctly, it is necessary to describe it for each browser.
d) HTML descriptions including sound and video differ depending on the browser.
Therefore, in order to support all browsers, it is necessary to describe a Web page
using only characters and still images.

programming language C, and has upper compatibility with C.
c) It is a markup language used on the Web and describes the document structure by
using tags. It enables the creation of hypertext that links text, movies, etc.
