The correct answer is option 'A', which means that the mother would show her daughter how her parents dressed her for the beach while showing her the photograph. Let's discuss why this is the correct answer in detail.

- **Introduction:**
The mother is showing her daughter a photograph, indicating that she wants to share some information or memories related to the image. The options provided give us different possibilities of what the mother could be showing or discussing.

- **Option A: How her parents dressed her for the beach:**
This option suggests that the mother wants to show her daughter how her parents dressed her for the beach. This could mean that the photograph captures a moment from the daughter's childhood when she went to the beach with her parents. By showing her daughter this photograph, the mother is likely reminiscing about the past and sharing a memory of how they used to dress her for beach outings.

- **Option B: Her cousins:**
This option suggests that the mother is showing her daughter a photograph of her cousins. While it is possible that the mother may want to share information about her daughter's cousins, this does not directly relate to the context of how her parents dressed her for the beach. Therefore, this option is not the correct answer.

- **Option C: Her own childhood photograph:**
This option suggests that the mother is showing her daughter a photograph of her own childhood. While it is possible that the mother may want to share information about her own childhood with her daughter, this does not directly relate to the context of how her parents dressed her for the beach. Therefore, this option is not the correct answer.

- **Option D: The background:**
This option suggests that the mother is showing her daughter the background of the photograph. While the background of a photograph can sometimes hold significance, it is unlikely that the mother would focus on showing her daughter the background rather than the main subject of the photograph. Therefore, this option is not the correct answer.

Considering all the options, option A is the most appropriate and relevant choice. It aligns with the context of the mother showing her daughter a photograph and provides a direct connection to the topic of how her parents dressed her for the beach.
