A) \[\left| x \right|<3\]
B) \[\left| x \right|\le 3\]
C) \[\left| x \right|>3\]
D)
\[\left| x \right|\ge 3\]

Solution :
[a] The shaded region in the figure lies between \[x=-3\] and \[x=3\] not including the line \[x=-3\] and \[x=3\] (lines are dotted) Therefore \[-3<x<3\] \[\Rightarrow \left| x \right|<3\] \[[\because \,\,\,\left| x \right|<a\Leftrightarrow -a<x<a]\]
