The point P(5, 7) is reflected to P' in x-axis and O' is the image of O (origin) in the line PP'. The co-ordinates of O' are :
(10, 0)
(0, 10)
(10, 10)
(5, 5)

Answer
We know that,
On reflection in x-axis, the sign of y-coordinate changes.
P(5, 7) = P'(5, -7)
Steps of construction :
Mark point P and P' in the graph.
Join the points to form line PP'.
From origin (O) draw a straight perpendicular line to PP' and produce. On this line mark a point O' which is at same distance as point O.
From figure,
O' = (10, 0).
Hence, Option 1 is the correct option.
