So, Option A is correct option.
Step-by-step explanation:
We are given function 
We need to find transformation g(x)
if f(x) is reflected on x-axis and a vertical translation 5 units down.
Finding the transformation:
if f(x) is reflected on x-axis
then g(x) will be - f(x) i.e

a vertical translation 5 units down.
Then g(x) will be f(x)-5
So,

So, Option A is correct option.
