Can a standard multimeter measure different types of variables with attachments?

A standard multimeter can indeed measure different types of variables such as voltage, current, and resistance, and with the appropriate attachments and adapters, it can also measure other parameters like temperature, capacitance, and frequency. This versatility is a key feature of multimeters, as they are designed to be multifunctional.

By using specific attachments, such as temperature probes or clamp-on current sensors, a multimeter can expand its capabilities beyond just basic electrical measurements. Adapters can facilitate connections for different types of sensors or input variations, allowing the multimeter to read and interpret a wider range of data.

While other choices may suggest limitations, a well-equipped multimeter's adaptability is what makes option B the ideal choice. Multimeters are a valuable tool in instrumentation due to their ability to provide a comprehensive set of measurements through various attachments, enhancing their overall functionality in diverse applications.
