From the given contour plot of a geographical region, we get

  • Height of point P > 575 m
  • Height of point R < 425 m
  • Height of point Q is in between 475 m to 500 m 
  • Height of point S is in between 500 m to 525 m 
  • Height of point T is in between 500 m to 525 m

among PQ, PR, PS and PT the one with largest height difference will be the steepest path.

since R is at lowest height , so path from P to R will be steepest path.

Correct Answer: B. $P$ to $R$
