Explanation:
If both lines are parallel, then their slopes must be equal.
For the line PQ, the slope is:
Slope of PQ = </span>

--- (1)
For the line P'Q', the slope is:
Slope of P'Q' =
Slope of P'Q' =

--- (2)
As (1) = (2), hence the lines are parallel and their slope is

(Option A).

The ratio of the height to shadow length is a constant.
.. (5 ft)/(132 ft) = (tree height)/(144 ft)
.. (tree height) = (144 ft)*(5/132) = 5 5/11 ft
