The correct answer is option 'D' - Saturday.

Explanation:

Sophie and her family go to watch the football match on Saturday. Here are the reasons why Saturday is the correct answer:

1. Context: The question mentions that Sophie and her family go to watch the football match. In order to determine the day, we need to consider the typical schedule for football matches.

2. Football matches: In many countries, football matches are commonly held on weekends, particularly on Saturdays and Sundays. This is because weekends provide an opportunity for people to gather and enjoy the game without the constraints of work or school.

3. Sunday options: The options provided in the question include Sunday morning, Sunday evening, and Sunday afternoon. While it is possible for football matches to be scheduled on Sundays, none of the given options specify Sunday as the correct day.

4. Saturday option: The only option that mentions a day other than Sunday is option 'D' - Saturday. This option aligns with the typical scheduling of football matches on weekends.

5. Logical reasoning: Considering that Sophie and her family go to watch the football match, it is more likely for them to attend the match on a Saturday rather than a Sunday, as weekends are usually preferred for such recreational activities.

In conclusion, based on the context and logical reasoning, it can be determined that Sophie and her family go to watch the football match on Saturday.
