What are two unique features of fat-arrow functions compared to normal function definitions?

Arrow functions have two defining characteristics:

Implicit return when written as a single expression:

const fn = () = > 5; // returns 5 automatically

This is unique to arrow functions → A is correct.

Lexical this binding : Arrow functions do not create their own this. Instead, they use the this value from the surrounding scope → B is correct.

Incorrect options:

C is false: There is no special argument called parentThis.

D is the opposite of arrow function behavior: Normal functions create their own this; arrow functions do not.
