A group of five items is given. Four of them share the common features...
Explanation:

The given question is a test of pattern recognition. We need to identify the item that is different from the others based on a common feature.

Let's analyze each option to determine the pattern:

a) 16 : 7
The common feature here is that the second number is 7, which is the result of dividing the first number (16) by 2.

b) 30 : 14
The common feature here is that the second number is 14, which is the result of dividing the first number (30) by 2.

c) 40 : 20
The common feature here is that the second number is 20, which is the result of dividing the first number (40) by 2.

d) 42 : 20
The common feature here is that the second number is 20, which is the result of dividing the first number (42) by 2.

Conclusion:

Based on the analysis, we can see that all options except option C have the second number as the result of dividing the first number by 2. However, in option C, the second number (20) is not the result of dividing the first number (40) by 2. Therefore, option C is the item that is different from the others.
