a.

To reduce the number of participants required.

b.

To observe how participants interact with the icons in their natural environment.

c.

To control variations in learning style between participants.

d.

To avoid transfer of learning effects.

Answer: (c).To control variations in learning style between participants. Explanation:A within-subjects design is chosen to control variations in learning style between participants and to minimize the effects of individual differences on the results.
