Explanation:

The given number series is: 33, 321, 465, 537, 573, 590, 600

To find the wrong number, we need to analyze the pattern followed by the given numbers. Let's break down the series and identify the pattern:

1. First number: 33
- It is a two-digit number.

2. Second number: 321
- It is a three-digit number.
- The second number is formed by reversing the digits of the first number and then adding 30. (33 reversed is 33, and adding 30 gives 63)

3. Third number: 465
- It is a three-digit number.
- The third number is formed by reversing the digits of the second number and then adding 30. (321 reversed is 123, and adding 30 gives 153)

4. Fourth number: 537
- It is a three-digit number.
- The fourth number is formed by reversing the digits of the third number and then adding 30. (465 reversed is 564, and adding 30 gives 594)

5. Fifth number: 573
- It is a three-digit number.
- The fifth number is formed by reversing the digits of the fourth number and then adding 30. (537 reversed is 735, and adding 30 gives 765)

6. Sixth number: 590
- It is a three-digit number.
- The sixth number is formed by reversing the digits of the fifth number and then adding 30. (573 reversed is 375, and adding 30 gives 405)

7. Seventh number: 600
- It is a three-digit number.
- The seventh number is formed by reversing the digits of the sixth number and then adding 30. (590 reversed is 95, and adding 30 gives 125)

Conclusion:

From the analysis above, we can observe that the pattern is to reverse the digits of the previous number and add 30 to it. However, the given series does not follow this pattern for the number 590. Therefore, the wrong number in the given series is 590.

Hence, the correct answer is option 'D' - 590.
