To answer this question, you need to understand the concept of a web service.
A web service is a software system designed to support interoperable machine-to-machine interaction over a network. It is a collection of functions or methods that can be accessed remotely over the internet using standard protocols such as HTTP.
The statement "A Web service is a function/method exposed on the web" is incorrect. A web service is not just a single function or method. It is a collection of functions or methods that can be accessed remotely.
Therefore, the correct answer is B) False.
