Set A consists of "children between the ages of 3 and 7," which means it includes children who are at least 3 years old and up to and including 7 years old.
Now let's look at each option and see if it meets the criteria:
a. "Children over 7" refers to children who are older than 7. Since set A only includes children up to and including 7 years old, this option is not a subset of set A.
b. "Children 3 years old" refers to children who are exactly 3 years old. Since set A includes children who are at least 3 years old, this option is a subset of set A.
c. "Children of all ages" refers to children of any age, including those older than 7 or younger than 3. Since set A specifically includes children between the ages of 3 and 7, this option is not a subset of set A.
d. "Children under 3" refers to children who are younger than 3. Since set A includes children who are at least 3 years old, this option is not a subset of set A.
Therefore, the correct answer is b. "Children 3 years old," as it is the only option that is a subset of set A.
