Let's analyze the given data step-by-step to compare the percentage of children and adults who use the toothpaste.

We are given:
- Of the adults surveyed, [tex]\( 11\% \)[/tex] use the toothpaste.
- In the table, for children, [tex]\( 0.06 \)[/tex] (or [tex]\( 6\% \)[/tex]) use the toothpaste.

Now, let's understand the question and the provided options:

1. Given Percentage for Children:
- From the table, for children, [tex]\( 0.06 \)[/tex] (or [tex]\( 6\% \)[/tex]) use the toothpaste.

2. Given Percentage for Adults:
- From the problem statement, about [tex]\( 11\% \)[/tex] of adults use the toothpaste.

The options provided for the percentage of children who use the toothpaste are:
- A: A smaller percentage of children ([tex]\( 8\% \)[/tex]) use the toothpaste.
- B: A greater percentage of children ([tex]\( 24\% \)[/tex]) use the toothpaste.
- C: A greater percentage of children ([tex]\( 40\% \)[/tex]) use the toothpaste.
- D: A smaller percentage of children ([tex]\( 6\% \)[/tex]) use the toothpaste.

Clearly, the percentage of children who use the toothpaste is [tex]\( 6\% \)[/tex], which corresponds to option D.

Thus, the true statement is:
D. A smaller percentage of children ([tex]\( 6\% \)[/tex]) use the toothpaste.
