Is m = 5?
(1) (m - 5)(n - 6) = 0
(2) (n - 6) = 0
(1) (m - 5)(n - 6) = 0
(2) (n - 6) = 0

From Statement (1): (m - 5)(n - 6) = 0 either (m - 5) = 0 or (n-6)=0, m = 5 or n = 6 So not Sufficient.
From Statement (2) (n - 6) = 0, n = 6. No Information about m, So not Sufficient.
By combining both statement.
(m - 5)(n - 6)= 0 & (n-6)= 0
Definitely n = 6 and m can be 5, not surely 5, m can be any real number.
So not Sufficient.
Hence option (E) is Correct.

Pure algebraic questions are no longer a part of the DS syllabus of the GMAT.
DS questions in GMAT Focus encompass various types of word problems, such as:
- Word Problems
- Work Problems
- Distance Problems
- Mixture Problems
- Percent and Interest Problems
- Overlapping Sets Problems
- Statistics Problems
- Combination and Probability Problems
While these questions may involve or necessitate knowledge of algebra, arithmetic, inequalities, etc., they will always be presented in the form of word problems. You won’t encounter pure "algebra" questions like, "Is x > y?" or "A positive integer n has two prime factors..."

You can also visit the Data Sufficiency forum and filter questions by OG 2024-2025, GMAT Prep (Focus), and Data Insights Review 2024-2025 sources to see the types of questions currently tested on the GMAT.
So, you can ignore this question.
Hope it helps.
