Q. Software coupling involves dependencies among pieces of software called modules. Which of the following are correct statements with respect to module coupling?

P: Common coupling occurs when two modules share the same global data.
Q: Control coupling occurs when modules share a composite data structure and use only parts of it.
R: Content coupling occurs when one module modifies or relies on the internal working of another module.
