If \(m_1, m_2, m_3\) and \(m_4\) are respectively the magnitudes of the vectors
\(\overrightarrow{\mathbf{a}}_1=2 \hat{\mathbf{i}}-\hat{\mathbf{j}}+\hat{\mathbf{k}}, \quad \overrightarrow{\mathbf{a}}_2=3 \hat{\mathbf{i}}-4 \hat{\mathbf{j}}-4 \hat{\mathbf{k}}\),
\(\overrightarrow{\mathbf{a}}_3=\hat{\mathbf{i}}+\hat{\mathbf{j}}-\hat{\mathbf{k}} \quad\) and \(\quad \overrightarrow{\mathbf{a}}_4=-\hat{\mathbf{i}}+3 \hat{\mathbf{j}}+\hat{\mathbf{k}}\),
then the correct order of \(m_1, m_2, m_3\) and \(m_4\) is
- A \(m_3 < m_1 < m_4 < m_2\)
- B \(m_3 < m_1 < m_2 < m_4\)
