When substituting a=7 and b=4 into the given equation, we get a^2 - b^2 = 7^2 - 4^2 = 49 - 16 = 33. Therefore, the value of a^2 - b^2 is 33, making option D the correct answer.

Option A is incorrect because it is the difference of a^2 and b^2, not the value of their difference.

Option B is incorrect because it is the sum of the values of a^2 and b^2, not the value of their difference.

Option D is incorrect. Although it is the correct value, it is stated differently from option C and may confuse the reader.
