and

(\overrightarrow i - \overrightarrow j - \overrightarrow k )

View answer and explanation

Correct option: A

{\sin ^{ - 1}}\frac{{\sqrt 8 }}{3}

Option A (

{\sin ^{ - 1}}\frac{{\sqrt 8 }}{3}

) is correct because it is the angle calculated using the dot product formula and the relationship between dot product and sine of the angle.
