A body projected at an angle with the horizontal has a range 300 m. If the time of flight is 6 s, then the horizontal component of velocity is

• A. \[30\text{ m}\,\,{{\text{s}}^{-1}}\]       
• B.        \[50\text{ m}\,\,{{\text{s}}^{-1}}\]
• C. \[40\text{ m}\,\,{{\text{s}}^{-1}}\]             
• D.        \[45\text{ m}\,\,{{\text{s}}^{-1}}\]
