Solution

The direct way to create a new object that inherits from an existing object's prototype is A) Object.create(existingObject).

Here's a step-by-step explanation:

  1. The Object.create() method is used in JavaScript to create a new object, using an existing object as the prototype of the newly created object.

  2. Object.create() takes the existing object as an argument and returns a new object that inherits all the properties and methods of the existing object.

  3. So, if you have an existing object and you want to create a new object that inherits from this existing object's prototype, you can use Object.create(existingObject).

  4. The other options B) new existingObject(), C) existingObject.spawn(), and D) existingObject.extend() are not standard ways to directly create a new object that inherits from an existing object's prototype in JavaScript.
