To rationalise the denominator, this is a standard step:
Answer: Option A

Let me continue to complete the question, though it is not ask for
How do I️ know if it is a A or D?
1 answer:
Answer is D.
y intercept is a constant (represented by 'd'), so set x=0 in each case.
for A,
the function at the y intercept is not equal to variable d.
whereas for D,
this answer shows that d is the solution to the equation at the y intercept.
of course the solution to B and C are
So they can't be right either.
so D is the answer.
