A contour line joins locations having the same height above the mean sea level. The following is a contour plot of a geographical region. Contour lines are shown at $25$ m intervals in this plot.
Which of the following is the steepest path leaving from $P$?
From the given contour plot of a geographical region, we get
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 $R$
