Explanation:

Step1: Understand balance principle

For a mobile to remain balanced, equal changes must be made to both sides.

Step2: Analyze option A

Adding a pentagon to both sides keeps the balance as equal weight is added to each side.

Step3: Analyze option B

Adding 5 leaves to both sides keeps the balance as equal weight is added to each side.

Step4: Analyze option C

Moving all pentagons to one - side changes the distribution of weight and will unbalance the mobile.

Step5: Analyze option D

Switching the leaf and circle changes the weight distribution on each side and will unbalance the mobile.

Step6: Analyze option E

Adding a circle to only the right - side changes the weight and will unbalance the mobile.

Step7: Analyze option F

Removing one pentagon from both sides keeps the balance as equal weight is removed from each side.

Answer:

A. Add a pentagon to both sides, B. Add 5 leaves to both sides, F. Remove one pentagon from both sides
