What is the name for tools that perform services?

• A. Implements
• B. Instruments
• C. Devices
• D. Equipment

Answer: (A)

The idea here is naming the kind of tools used to carry out a task or service. Implies practical, hand-held items specifically designed to perform work for a service. This term fits best because it directly signals tools built to carry out a function. Other terms have different nuances: instruments often refer to precise or delicate tools used for measurement or specialized work; devices are gadgets or machines; equipment denotes the entire set of tools needed for a job. So for tools that perform services, the term implements is the most appropriate.
