In the parallelogram \( ABCD \) shown in the picture, \( G \) is the midpoint of \( CD \), \( F \) is the midpoint of \( BC \) and \( \overrightarrow{u}=\overrightarrow{CG} \), \( \overrightarrow{v}=\overrightarrow{CF} \), \( \overrightarrow{a}=\overrightarrow{AD} \) and \( \overrightarrow{b}=\overrightarrow{AC} \). Express vectors \( \overrightarrow{a} \) and \( \overrightarrow{b} \) as a linear combination of vectors \( \overrightarrow{u} \) and \( \overrightarrow{v} \).
\( \overrightarrow{a}=-2\overrightarrow{v};\ \overrightarrow{b}=-2\overrightarrow{u}-2\overrightarrow{v} \)
\( \overrightarrow{a}=\overrightarrow{b}+2\overrightarrow{u};\ \overrightarrow{b}=-2\overrightarrow{u}+2\overrightarrow{v} \)
\( \overrightarrow{a}=\overrightarrow{b}-2\overrightarrow{u};\ \overrightarrow{b}=-\sqrt2\overrightarrow{u}-\sqrt2\overrightarrow{v} \)
\( \overrightarrow{a}=-2\overrightarrow{v};\ \overrightarrow{b}=2\overrightarrow{u}+2\overrightarrow{v} \)
