    Answer:

    The correct option is (b). The treatment variable is riding a bike to school. The outcome variable is the child’s attention span.

    Step-by-step explanation:

    So here riding a bike to school is the Treatment variable because this can be manipulated by ht e researchers.

    Outcome variables: The outcome variables are dependent on the independent variables.

    Here, attention span is depending on the treatment variable.

    Therefore, the correct option is (b). The treatment variable is riding a bike to school. The outcome variable is the child’s attention span.
