If the internal radius of a hollow shaft is n times the external radius, then ratio of torques carried by the hollow shaft and solid shaft of same cross-section area and subjected to the same maximum shearing stress is

- 1
  
  $1 - n^{4}$
- 2
  
  $\frac{1 + n^{2}}{1 - n^{2}}$
- 3
  
  $\frac{\sqrt{1 + n^{2}}}{1 - n^{2}}$
- 4
  
  $\frac{1 + n^{2}}{\sqrt{1 - n^{2}}}$
