this.props refers to that storage object. At the same time, each piece of passed-in information is called...

• A. a state
• B. a prop
• C. a component
• D. a child

Answer: (B)

The main idea here is props. In React, components receive inputs called props from their parent, and this.props is the object that holds all those inputs. Each piece of information passed in is a prop—the individual values you access inside the component as this.props.name, this.props.color, and so on. Props flow data from parent to child and are read-only from the child’s perspective, unlike state, which is internal and can change over time. A component is the building block you render, while a child is a nested component or element inside another component; the important point here is that the individual pieces of data you pass in are props.
