Correct answer: (d) Neither 1 nor 2
Explanation
- A
1 only
(a) 1 only. Statement 1 is false: LTE is marketed as 4G, not 3G, and VoLTE is voice-over-4G, not “advanced 3G”. Not the key.
- B
2 only
(b) 2 only. Statement 2 is false: LTE carries data (and, with VoLTE, packet voice). VoLTE is not a voice-only technology that replaces data. Not the key.
- C
Both 1 and 2
(c) Both 1 and 2. Both differences as worded are false. Not the key.
- D
Neither 1 nor 2
(d) Neither 1 nor 2. LTE is 4G data; VoLTE is voice (and SMS) as packets on the LTE bearer, so you can use data during a call. Neither listed “difference” is right. That is the official key.
Summary. Official key is (d). LTE is the 4G radio standard, commonly sold as 4G LTE. VoLTE puts voice on that same IP pipe; it is not a separate voice-only or 3G product. Both statements fail. Honour (d).
