Hello!

(4m^2 - 5)(4m^2 + 5) 

You have to multiply each term from the parenthesis together, and add up the four terms.  You may have heard of the expression FOIL (first, outer, inner, last)

16m^4 + 20m^2 - 20m^2 - 25

Now you can cancel out the middle two terms to arrive at your answer.

16m^4 - 25

Answer is A.

Let me know if you have any questions :)
