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 \[{{P}_{x}}=2\,\cos t,\] \[{{P}_{y}}=2\sin t\]. The angle \[\theta \] between \[\overrightarrow{F}\] and \[\overrightarrow{P}\] at a given time t will be

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