Knowledge of Computer ApplicationsInternet and communication
- A1 and 3 only
- B1 only
- C3 only
- D2 only
Explanation
A “Generation” denotes the technology standard era, not subscriber counts (1 is false). 2G indeed has two dominant standards — GSM and CDMA/IS-95 (2 is true). Statement 3 is false: 3G comprises UMTS/WCDMA (GSM lineage) and CDMA2000 (CDMA lineage), not “GSM” alone. Hence 2 only — option (D).
