If \overline{a}=\overline{ {\i}}-\overline{ {\j}}+\overline{ {\k}}, \overline{b}=\overline{ {\i}}+\overline{ {\j}}-2 \overline{ {\k}}, \overline{c}=2 \overline{ {\i}}-3 \overline{ {\j}}-\overline{ {\k}}, \overline{d}=2 \overline{ {\i}}+\overline{ {\j}}+\overline{ {\k}} are four vectors then (\overline{a} \times \overline{c}) \times(\overline{b} \times \overline{d})= [AP EAPCET 21 May 2024 Shift 1]

Correct Answer is : −8i+j−29k

2 \overline{ {\i}}+19 \overline{ {\j}}-11 \overline{ {\k}}

-8 \overline{ {\i}}+19 \overline{ {\j}}-29 \overline{ {\k}}

2 \overline{ {\i}}+\overline{ {\j}}-11 \overline{ {\k}}

-8 \overline{ {\i}}+\overline{ {\j}}-29 \overline{ {\k}}
