Explanation:

The figure given in the question appears to be a Venn diagram, which is used to represent relationships between sets. In this case, there are four sets labeled as a, b, c, and d. The diagram shows the intersection between these sets, which means the overlapping regions between them.

We can see that the intersection between sets c and d is shaded in the diagram. This means that there are elements that belong to both sets c and d. However, there is no shading in the other regions, which means that the other intersections are empty.

To identify which option represents this diagram, we need to look at the choices given. Option 'A' shows shading in the intersection between sets a and b, but this is not present in the given diagram. Option 'B' shows shading in the intersection between sets b and c, but this is also not present in the given diagram.

Option 'C' shows shading in the intersection between sets c and d, which is the same as the given diagram. Therefore, option 'C' is the correct answer.

Option 'D' shows shading in the intersection between sets a and d, but this is not present in the given diagram. Hence, option 'D' is incorrect.

Final Answer: Option 'C'.
