Explanation:

- Original set: {25, 19, 36}. These are not prime numbers and have no obvious mathematical relationship such as squares, cubes, or arithmetic sequences.

- Option 1: {9, 49, 16}. These are perfect squares: 3², 7², and 4².

- Option 2: {20, 28, 32}. These aren't special forms like squares but consider number type.

- Option 3: {30, 25, 35}. These numbers are random in arithmetic terms but not perfect squares or cubes.

- Option 4: {36, 23, 48}. Includes a perfect square 6² and other numbers with no arithmetic connection.

The most similar to the original set is Option 3: {30, 25, 35}, no special patterns, just random composition.

The correct answer is Option 3: {30, 25, 35}.
