Ai-a, ii-b, iii-c, iv-d

Bi-c, ii-b, iii-d, iv-a ✓ Correct

Ci-b, ii-c, iii-a, iv-d

Di-d, ii-a, iii-c, iv-b

Correct answer: (B) i-c, ii-b, iii-d, iv-a

Explanation

Authentication verifies that data comes from a trusted source and works with encryption to strengthen security.

Biometrics relies on unique human characteristics such as retina or fingerprint scans.

An IP address identifies where on the network a device is located.

A MAC address identifies which specific device is connected at a given IP address.

Swapping the IP and MAC descriptions is the common trap, since both are addressing terms.

A MAC address is fixed to the hardware, while an IP address can change with the network.
