public class Zoo

... }

Explanation:

The question is an illustration of inheritance in Java programming language.

The syntax to follow is:

class subclass extends superclass {...}

From the question:

Bear subclass

Animal superclass

So, the following declaration will be used:

class Bear  extends Animal{ ... }

Also from the question, the zoo object represents collection of many animals.

So, its declaration will follow:

class class-name{ ..... }

i.e.

class zoo{ .... }

The ... can then be replaced with declaration of each animal or an array to represent the declarations..

Hence, (e) is correct
