Answer
We know that,
On reflecting in origin the sign of both x and y co-ordinate changes.
Let on reflection in origin P(-14, -18) becomes P'.
P(-14, -18) ⇒ P'(14, 18).
We know that,
On reflecting in x-axis, the sign of y co-ordinate changes.
Let on reflection in x-axis, P'(14, 18) becomes P".
P'(14, 18) ⇒ P"(14, -18).
Hence, Option 2 is the correct option.
