Statement I :Two forces $\left( {\overrightarrow P + \overrightarrow Q } \right) and \left( {\overrightarrow P - \overrightarrow Q } \right) where \overrightarrow P \bot \overrightarrow Q , when act at an angle \theta1 to each other, the magnitude of their resultant is \sqrt {3({P^2} + {Q^2})} , when they act at an angle \theta2, the magnitude of their resultant becomes \sqrt {2({P^2} + {Q^2})} . This is possible only when {\theta _1} < {\theta _2}.Statement II :In the situation given above.\theta1 = 60^\circ and \theta2 = 90^\circ$In the light of the above statements, choose the most appropriate answer from the options given below :-
