3G and 4G are wireless technologies, which are supposedly faster, more secure and reliable. Present day 3G technology is capable of handling data around 2 Megabits per second (1.8 – 2.5 GHz frequency band). What speed is expected from new 4G technology ?
10-30 Megabits per second (1-5 GHz frequency band)
10-100 Megabits per second (2-10 GHz frequency band)
100 Megabits—1 Gigabit per second (2-8 GHz frequency band)
More than 10 Gigabits per second (10-20 GHz frequency band)
Answer is Right!

LTE (4G) typically aims for peak downlink speeds of 100 Mbps for high-mobility users and up to 1 Gbps for low-mobility users (in advanced versions like LTE-Advanced). Peak uplink speeds are lower, typically up to 50 Mbps.
Comparing the options:
A) 10-30 Mbps: Only slightly better than 3G, too low for 4G targets.
B) 10-100 Mbps: Covers the lower end of 4G peak downlink but doesn’t capture the higher potential.
C) 100 Megabits—1 Gigabit per second: This range accurately reflects the peak theoretical speeds achievable by 4G and LTE-Advanced technologies, particularly the upper bound in ideal conditions.
D) More than 10 Gigabits per second: This speed range is characteristic of 5G technology, not 4G.
The frequency band mentioned (2-8 GHz) is also plausible for 4G deployments, although 4G uses various bands depending on the region and spectrum availability.
