In the context of Bluetooth and Wi-Fi as wireless communication technologies, which of the following statements are true? Choose the correct answer from the options given below.

1.Bluetooth allows short-range data transfer between electronic devices, whereas Wi-Fi allows electronic devices to connect to the Internet.

2.Bluetooth needs a direct line of sight for data transmission, whereas Wi-Fi does not.

3.Bluetooth limits the number of devices that can connect at one time, whereas Wi-Fi is open to more devices and users.

4.Bluetooth does not need a direct line of sight for data transmission, whereas Wi-Fi does.

A1, 2 only

B2, 3 only

C1, 3, 4 only

D1, 3 only ✓ Correct

Correct answer: (D) 1, 3 only

Explanation

Bluetooth handles short-range transfer between devices while Wi-Fi connects devices to the internet, making Statement 1 true.

Statement 3 is also true because Bluetooth limits how many devices connect at once while Wi-Fi supports far more users.

Statement 2 is false because Bluetooth does not need a direct line of sight to transmit data.

Statement 4 is false because Wi-Fi also works without a direct line of sight.

Both are wireless, but Bluetooth suits close pairings and Wi-Fi suits network access.

Bluetooth typically reaches about ten metres, far less than a Wi-Fi network.
