If \(\overrightarrow{a}, \overrightarrow{b}, \overrightarrow{c}\) are non-coplanar unit vectors such that \(\overrightarrow a\,\times \,\left( {\overrightarrow b \times \overrightarrow c } \right) = \,\frac{{\left( {\overrightarrow b \, + \,\overrightarrow c } \right)}}{{\sqrt 2 }}\), then the angle between \(\overrightarrow{a}\) and \(\overrightarrow{b}\) is
1
\(\frac{3π}{4}\)
2
\(\frac{π}{4}\)
3
π/2
4
π
