Long-Term Evolution (LTE), marketed as 4G LTE, is a standard for wireless broadband communication for mobile devices and data terminals. It was specifically designed to provide significantly higher data transfer speeds and lower latency compared to its predecessors. For activities like streaming high-definition videos, which require a consistent, high-bandwidth connection, LTE is the most suitable technology among the options provided. It ensures the smooth, buffer-free experience Sarah desires during her commute.

B. Time Division Multiple Access (TDMA) is a 2G cellular technology with very low data rates, making it unsuitable for video streaming.

C. Enhanced Data Rates for GSM Evolution (EDGE) is a pre-3G technology (2.75G) that offers an improvement over GPRS but is still far too slow for HD video.

D. Code Division Multiple Access (CDMA) is a channel access method used in 2G and 3G standards; while 3G offered improvements, it lacks the speed of 4G LTE.
