Where is React.Component defined?

• A. As a property on the object returned by importing React from 'react'
• B. In the DOM API
• C. Global browser function
• D. In CSS

Answer: (A)

React.Component is defined inside the React library you import from 'react'. When you do import React from 'react', you get a React object and Component is a property on that object, so you can write class MyComponent extends React.Component. It isn’t part of the DOM API, a global browser function, or something in CSS. You can also import { Component } from 'react' to use it directly as a base class.
