The degree measure of 1 radian is :
[A]$57\textdegree32'16''$
[B]$57\textdegree61'22''$
[C]$57\textdegree16'22''$
[D]$57\textdegree22'16''$

$\mathbf{57\textdegree16'22''}$
$\therefore 1 radian = \frac{180\textdegree}{\pi}$
$= \frac{180\times7\textdegree}{22}$
$= \frac{630}{11} = 57\frac{3}{11}\textdegree$
$= 57\textdegree\frac{3}{11}\times 60' = 57\textdegree\frac{180'}{11}$
$= 57\textdegree16'\frac{4}{11}\times 60'' = 57\textdegree16'22''$
Hence option [C] is the right answer.
