PQR is a triangle in which\[\angle \mathbf{Q}\text{ }=\text{ }\mathbf{2}\angle \mathbf{R}\]. If a line PS is drawn from vertex P such that it bisects \[\angle \mathbf{QPR}\] and cuts QR at S such that \[\mathbf{PQ}\text{ }=\text{ }\mathbf{RS}\], then \[\angle \mathbf{QPR}\text{ }+\text{ }\angle \mathbf{QRP}\] equals to __________

• A. \[72{}^\circ \]                                                              
• B. \[136{}^\circ \]        
• C. \[108{}^\circ \]            
• D. \[130{}^\circ \]
• E. None of these.
