Which statement about coupling is true?

• A high level of coupling will make your code more maintainable

• A low level of coupling will enhance the performance of your code.

• The level of coupling doesn't matter, as long as the cohesion is high.

• A low level of coupling will make your code more maintainable.

In object oriented programming, the Open-Closed principle states that:

• Software elements should be open for extension, but closed for modification

• Software elements should be open for modification, but closed for extension.

• Dependencies of your software elements should go from concrete elements to abstract elements.

• Dependencies of your software elements should go from abstract elements to concrete elements.
