Which statement about passing props is correct?

• A. Props are immutable and cannot be changed by the child.
• B. Props are passed using a global variable.
• C. Props can be passed by rendering the child element with props.
• D. Props can only be used for styling.

Answer: (C)

Props in React are a way for a parent to pass data to a child by rendering the child component with attributes. You provide values like <Child data={value} onSubmit={handleSubmit} /> and the Child receives them as a props object to read and use in rendering or logic. This means the mechanism described—passing props by rendering the child element with props—is the correct one because it directly shows how data gets from parent to child. In practice, props are read-only for the child; you shouldn’t mutate them. If the child needs to request changes, it should call a function passed down from the parent, letting the parent manage the state. Props aren’t global variables, and they aren’t limited to styling—any data or callbacks can be passed through props.
