Final answer:
A feature of smart devices is gathering information such as location and position. Smart devices also enable communication with others and can have offline capabilities. While some devices consume energy, advancements in battery technology have improved energy efficiency.
Step-by-step explanation:
A feature of smart devices is gathering information such as location and position. For example, smartphones have GPS capabilities that can pinpoint the user's location and provide directions. This feature is useful for navigation apps, ride-sharing services, and finding nearby points of interest.
In contrast to option b that suggests restricting communication to direct user commands, smart devices actually enable communication with others through various means such as phone calls, messaging apps, and social media.
While some smart devices consume a significant amount of energy when in use, advancements in battery technology have improved energy efficiency in many devices, resulting in longer battery life.
Option d suggests that smart devices have limited functionality in offline mode, but this is not necessarily the case. Many smart devices have offline capabilities and can still perform certain functions, such as playing offline media or accessing stored data.
