A stone is thrown from a point with a speed 5 m/s at an elevation angle of \[\theta \]. From the same point and at the same instant, a person starts running with a constant speed 2.5 m/s to catch the stone. If the person will be able to catch the ball then, what should be the angle of projection \[\theta \]?

• A. \[75{}^\circ ~~\]
• B. \[30{}^\circ \]
• C. \[60{}^\circ \]
• D. \[45{}^\circ \]
