$\overrightarrow{a}$,$\overrightarrow{b}$,$\overrightarrow{c}$ are three orthogonal vectors. Given that $\overrightarrow{a}$ = ${\widehat{i}}$ + 2${\widehat{j}}$ + 5${\widehat{k}}$ and $\overrightarrow{b}$ = ${\widehat{i}}$ + 2${\widehat{j}}$ – ${\widehat{k}}$, the vector $\overrightarrow{c}$ is parallel to
- $\widehat{i}+2\widehat{j}+3\widehat{k}$
- $2\widehat{i} + \widehat{j}$
- $2\widehat{i} – \widehat{j}$
- $4\widehat{k}$
