Answer
Given,
Let the point (-5, -8) be P.
We know that,
On reflecting in y-axis the sign of x-co-ordinate changes.
Let on reflection in y-axis, P(-5, -8) becomes P'.
P(-5, -8) ⇒ P'(5, -8).
We know that,
On reflecting in origin the sign of both x and y co-ordinate changes.
Let on reflection in origin, P'(5, -8) becomes P".
P'(5, -8) ⇒ P"(-5, 8).
Hence, Option 1 is the correct option.
