A.1 only
D.Neither 1 nor 2
C.Both 1 and 2
B.2 only
Correct Answer: Option C
Li-Fi (Light Fidelity) is a wireless communication technology that uses light to transmit data at high speeds.
Statement 1: Li-Fi uses visible light communication (VLC) for data transmission. This means it uses light as the medium, making the statement correct.
Statement 2: Li-Fi is indeed a wireless technology and offers significantly faster speeds than Wi-Fi. It has the potential to be 10 to 100 times faster than current Wi-Fi technologies.
Statement 1 is correct. Statement 2 is correct. Hence, both statements 1 and 2 are correct.
