Which among the following do/does not belong/belongs to the GSM family of wireless technologies ?

EDGE (Enhanced Data rates for GSM Evolution) is an enhancement of the GSM/GPRS family and is commonly described as part of the GSM evolution path (often termed 2.75G). LTE (Long Term Evolution) is a 3GPP-driven 4G mobile standard that evolved from earlier 3G/UMTS and HSPA technologies and represents the move beyond traditional GSM 2G/2.5G enhancements toward a packet‑optimized 4G air interface. DSL (Digital Subscriber Line), by contrast, is a wired broadband access technology delivered over telephone copper pairs and is not a wireless/mobile technology nor part of the GSM family. Therefore DSL does not belong to the GSM family of wireless technologies.
