Answer:
Option (3)
Explanation:
In a topographic map, the elevations are represented in the form of contour lines. This is the line of equal elevations. The more contrasting and highlighting contours are considered as index contours.
In the given map, the dark brown colored contours are the index contours, of which Y is the one. The elevation of this contour line is 3250.
The Z contour is at the left bottom portion of the topographic map and shows a lesser contour line of 2900. This can be identified by observing the river flowing downward. The rivers are usually denoted by the blue color line that flows through the V-shaped sequential arrangement of contours. This is one of the ways of determining the increasing and the decreasing direction of contour lines.
Thus, the elevation of Y and Z is 3250 and 2900 respectively.
Hence, the correct answer is option (3).
