Answer:
c. More restrictive than protected, but less restrictive than private
Explanation:
The default accessibility for members is more restrictive than protected accessibility but less restrictive than private. Members with default accessibility are only accessible within the class itself and from classes in the same package. Protected members are in addition accessible from sub-classes anywhere. Members with private accessibility are only accessible within the class itself.
