Laptops, all-in-one desktops, and smartphones usually have what feature?

• A. Internal microphones
• B. External microphones
• C. Both
• D. None

Answer: (A)

Built-in audio input is standard on most portable devices, so you can speak into the device for calls, voice commands, and recordings without plugging in anything. Laptops, all-in-one desktops, and smartphones typically include a built-in microphone, making internal microphones the usual feature. External microphones can be used, but they’re optional accessories and not present by default on most devices. That’s why internal microphones are the best answer.
