A particle moves in the x-y plane under the action of a force \[\overrightarrow{F}\] such that the value of its linear momentum \[\overrightarrow{P}\] at any time t is \[{{p}_{X}}=2\] cos t and the angle \[\theta \] between \[\overrightarrow{F}\] and \[\overrightarrow{P}\] at any time t will be

• A.  \[90{}^\circ \]                                    
• B. \[0{}^\circ \]
• C. \[180{}^\circ \]                 
• D.        \[30{}^\circ \]
