(Refer to the figure below)
Mark the point P and Q on a graph.
Since, point R has x-coordinate as 7, draw a line of x = 7.
We have been given that the triangle cannot have any angle greater than 90° i.e. the y-coordinate of point R cannot go beyond the y value of point P (y = 5) and y value of point Q (y = 1).
The available options for y-coordinate of point R is 1, 2, 3, 4, and 5
Hence, option C
