1. Choose the word that is an essential part of the word - Mobile.
- A. Battery
- B. Battery
- C. Battery
- D. Battery
Answer: Option A
Explanation:
The correct answer is 1. Battery. A mobile device cannot function at all without a battery, as it provides the power needed for it to operate. While the other components are important for a mobile phone's utility, the battery is the most fundamental part that enables the device to be "mobile".
- Battery: A mobile phone would not be able to turn on or run without a battery, as it is the source of its power.
- Charger: A charger is an accessory used to recharge the battery, but it is not an essential part of the mobile device itself. The device can still function without a charger, provided the battery is not depleted.
- Internet: The internet is a service that a mobile phone can connect to, but it is not a physical part of the device. A mobile phone can still be a "mobile" device and perform other functions without internet access.
- Memory Card: A memory card is an optional component used for additional storage, but it is not required for the basic operation of the mobile phone. The device can function perfectly well without a memory card.
