(a) 1 and 2 only

(b) 3 only

(c) 1 and 3 only

(d) 1, 2 and 3

Answer: (c)        

Explanation:

• Near Field Communication (NFC) is a contactless communication technology based on an electromagnetic radio frequency (RF). Hence, Statement 1 is correct.
• NFC technology is designed for an operating distance of a few centimetres. Hence, Statement 2 is incorrect.
• This makes it more difficult for attackers to record the communication as compared to other wireless technologies which have a working distance of several meters.
• NFC can use encryption when sending sensitive information. Hence, Statement 3 is correct.
