Answer
Scenario (i) gives a larger shadow; scenario (ii) gives a smaller shadow.

Explanation

  • When the ball is closer to the torch, the shadow is larger.
  • When the ball is closer to the wall, the shadow is smaller.
  • So scenario (i) shows the bigger shadow (option a).
  • Scenario (ii) shows the smaller shadow (option b).
Nearer the torch means a bigger shadow; nearer the wall means a smaller one.
