Both the Statement 1 and Statement 2 are not correct.
Explanation
Hint:
The total number of electrons an atom can lose or gain to form a bond with other elements is called the oxidation state of that atom.
Explanation:
$$ x\ +\ (4\left ( -2 \right ))=-1$$ $$ \Rightarrow x=+7$$.
$$ y\ +\ (6\left ( -1 \right ))=-3$$ $$ \Rightarrow y=+3$$.
$$ z\ +\ (6\left ( -1 \right ))=-2$$ $$ \Rightarrow z=+4$$.
$$ q\ +\ (2\left ( -2 \right ))\ +\ (2\left ( -1 \right ))=0$$ $$ \Rightarrow q=+6$$.
Hence, $$ CrO_2Cl_2$$ has $$+6$$ oxidation state.
Therefore, the correct answer is option $$D.$$
