Final answer:
The correct answer to the question is b) The sensor is redundant, meaning that while the application uses a specific type of sensor, it does not depend on it for its primary functionality. This implies that the sensor serves as an additional component that could provide backup or enhance performance but is not essential to the operation of the application.
Step-by-step explanation:
If an application uses a specific type of sensor but does not rely on it for critical operations or processes, it means that the sensor is not crucial to the application's core functionality. Given the options provided:
- b) The sensor is redundant - This is the correct answer. Redundancy in technology means that a component is not necessary, but it is present as a backup or to improve performance under certain conditions. If the application can function without this sensor, its presence may be to provide additional data, improve accuracy under certain circumstances, or serve as a fallback should other primary sensors fail.
- a) The sensor is crucial - This would be the case if the sensor were essential to the operation of the application, which is not true in this scenario.
- c) The sensor is obsolete - This term refers to something that is out of date or no longer used. The question does not imply that the sensor is outdated, just that it is not essential for the application's function.
- d) The sensor is malfunctioning - This term refers to a sensor that is not working properly. The question does not provide any information about the sensor's functionality.
Therefore, the appropriate answer to the given question is b) The sensor is redundant.
