Which letter is on the steepest slope?

(A.) A

(B.) B

(C.) C

Letter B is on the steepest slope.

Explanation:

A is not correct because letter A is on a position where the contour lines are not close to each other, suggesting that the slope is not mild.

B is correct because the spacing between the contour lines where the letter B is marked is very small, suggesting that the slope is very steep.

wC is not correct because just like with letter A, the contour lines are not close to each other, but are further away, suggesting that the slope is not steep but it is mild.

the answers are a and c
