Correct Option (d)
Explanation
Statement 1 is incorrect. LTE (Long-Term Evolution) is a 4G (Fourth Generation) wireless communication standard, not 3G. It provides significantly higher data speeds and lower latency compared to 3G technologies. VoLTE (Voice over Long-Term Evolution) is a technology that enables voice calls to be made over the 4G LTE network, treating voice as data packets. It is not an advanced 3G technology; rather, it is a 4G service.
Statement 2 is incorrect. LTE is primarily designed for high-speed data transmission. However, when VoLTE is implemented, the LTE network also carries voice traffic as data packets. Therefore, LTE is not exclusively a data-only technology in the context of VoLTE. Similarly, VoLTE is not a voice-only technology. It allows for simultaneous voice calls and high-speed data usage on the 4G network, which was often not possible or was slower on older 2G/3G networks.
Incorrect Options
Options (a), (b), and (c) are incorrect because both statements 1 and 2 are factually inaccurate. Statement 1 incorrectly categorizes LTE and VoLTE as 3G technologies. Statement 2 incorrectly restricts LTE to data-only and VoLTE to voice-only functionalities, whereas both support broader capabilities within the 4G ecosystem, including simultaneous voice and data for VoLTE.
