Which of the following statements is false? a. Classes (and their objects) encapsulate, i. e., encase, their attributes and methods. b. A class’s (and its object’s) attributes and methods are intimately related. c. For objects to communicate effectively with one another, each must know how the other object is implemented. d. Information hiding is crucial to good software engineering.

The correct option is C: For objects to communicate effectively with one another, each must know how the other object is implemented.

Explanation:

For effective communication of objects with each other, there is no need for each object to know how the other object is implemented. The rules for communication are already defined, and hence you do not have to know, as details of implementation are hidden. Hence the only false statement from the options is C.
