The correct answer is: A constructor always has no cohesion.
A constructor is a special type of method that is used to initialize an object. It is called when an object is created, and it has access to the object’s private members.
Cohesion is a measure of how well the parts of a program are related to each other. A program with high cohesion is one in which each part of the program has a single, well-defined purpose. A program with low cohesion is one in which the parts of the program are not well-related to each other, and it may be difficult to understand how they work together.
A constructor always has no cohesion because it is used to initialize an object, and it does not have a single, well-defined purpose. The constructor may be used to initialize the object’s data members, to call other methods on the object, or to perform other tasks.
Communicational cohesion is a measure of how well the parts of a program communicate with each other. A program with high communicational cohesion is one in which the parts of the program communicate with each other in a clear and concise way. A program with low communicational cohesion is one in which the parts of the program communicate with each other in a complex and confusing way.
Temporal cohesion is a measure of how well the parts of a program are related to the time at which they are executed. A program with high temporal cohesion is one in which the parts of the program are executed in a logical order. A program with low temporal cohesion is one in which the parts of the program are executed in a random order.
Logical cohesion is a measure of how well the parts of a program are related to the logical structure of the program. A program with high logical cohesion is one in which the parts of the program are related to each other in a logical way. A program with low logical cohesion is one in which the parts of the program are not related to each other in a logical way.
