The X11 configuration file xorg.conf is grouped into sections, and the content of the section SectionName is associated with that section by placing it between a line containing Section "SectionName" and a line containing EndSection. For example, the following is a section named ServerLayout that defines the layout of the X server:
Section "ServerLayout" Identifier "X.org Configured" Screen 0 "Screen0" 0 0 InputDevice "Mouse0" "CorePointer" InputDevice "Keyboard0" "CoreKeyboard" EndSection The other options are incorrect for the following reasons:
A: Curly brackets are not used to delimit sections in xorg.conf. They are used to enclose values that are lists, such as Option "XkbLayout" "{us,fr}".
C: Tags are not used to delimit sections in xorg.conf. They are used in XML files, which have a different syntax and structure than xorg.conf.
D: Rows are not used to delimit sections in xorg.conf. They are used to define key-value pairs within a section, such as Identifier "Screen0".
E: Indentation is not required to delimit sections in xorg.conf. It is used to improve readability and clarity, but it does not affect the functionality of the file.
