Right Answer is: C
SOLUTION
Vertical cliff → Contour lines of different elevations unite to form one line.
Important Points:
Steep slope → Contour lines are closely spaced and for mild slope contour lines are apart from each - other.
Hill → Closed contour lines with higher values inside indicate hill and with lower values inside indicate pond or depression.
Overhanging cliff → Two contours of different elevation cannot cross each other except in case of vertical cliff.
