He needs a webcam and speakers so that he and his mother can both see and hear each other.

Why this is the right hardware

  • The webcam captures Alessandro’s video so his mother can see him.
  • The speakers (or a headset) play his mother’s voice so he can hear her.
  • Most desktops don’t include a built‑in webcam, so adding an external USB webcam plus speakers/headset is the standard setup for video chat.

In the multiple‑choice style versions of this question online, the correct option is: “Use his webcam and speakers so that he and his mother can both see and hear each other.”
