Grouping the Numbers

To solve this question, we need to find a pattern or a rule that divides the given numbers into groups. Let's observe the numbers closely and try to identify any pattern.

- 42624: This number has two pairs of identical digits (22 and 44). It belongs to the group of numbers with repeated digits.
- 37573: This number has two pairs of consecutive digits (37 and 57). It belongs to the group of numbers with consecutive digits.
- 84284: This number has two pairs of identical digits (88 and 44). It belongs to the group of numbers with repeated digits.
- 93339: This number has five identical digits (33333). It belongs to the group of numbers with repeated digits.
- 74347: This number has a palindrome pattern (74347). It belongs to the group of palindrome numbers.

Identifying the Odd One Out

Now that we have identified the groups, we need to find the number that does not belong to any of the groups. It is clear that all the given numbers belong to some group except for one. Let's analyze each option to find out which one does not fit into any of the groups.

Option (C) 84284: This number has two pairs of identical digits (88 and 44). It belongs to the group of numbers with repeated digits. Therefore, it does not stand out as an odd one out.

Hence, option (C) is the odd one out as all the other options belong to some group.
