Let |\overrightarrow{a}| \\neq0,|\overrightarrow{b}| \\neq0 (\overrightarrow{a}+\overrightarrow{b}) \.({a^{\to}}+\overrightarrow{b})=|\overrightarrow{a}|^{2}+|{b^{\to}}|^{2} Holds if and only if

Correct Answer is : →a and →b are perpendicular

\overrightarrow{a} and \overrightarrow{b} are perpendicular

\overrightarrow{a} and \overrightarrow{b} are parallel

\overrightarrow{a} and \overrightarrow{b} are inclined at an angle of 45^\circ

\overrightarrow{a} and \overrightarrow{b} are anti-parallel
