Explanation:

Step1: Count the frequency of each number of pets

• For \(0\): Count the number of \(0\)s in the data. There are \(15\) \(0\)s.
• For \(1\): Count the number of \(1\)s. There are \(10\) \(1\)s.
• For \(2\): Count the number of \(2\)s. There are \(6\) \(2\)s.
• For \(3\): Count the number of \(3\)s. There are \(4\) \(3\)s.
• For \(4\): Count the number of \(4\)s. There are \(3\) \(4\)s.
• For \(5\): Count the number of \(5\)s. There are \(2\) \(5\)s.

Step2: Match with the given tables

• Table \(a\) has frequencies \(15\) (for \(0\)), \(10\) (for \(1\)), \(6\) (for \(2\)), \(4\) (for \(3\)), \(3\) (for \(4\)), \(2\) (for \(5\)) which matches our counts.

Answer:

A.
