The correct answer is d. Neither 1 nor 2.

LTE (Long-Term Evolution) is a standard for wireless broadband communication for mobile devices and data terminals, while VoLTE (Voice over Long-Term Evolution) is a technology that enables voice calls over LTE networks. Both LTE and VoLTE are marketed as 4G technologies, not 3G. Therefore, statement 1 is incorrect.

Furthermore, statement 2 is also incorrect, as LTE is not a data-only technology, and VoLTE is not a voice-only technology. While LTE primarily supports data, it can also be used for voice calls using technologies such as Voice over IP (VoIP). Similarly, VoLTE primarily supports voice calls but can also be used for data services.
