When combining my own OOP class with work done by someone else, what is the main $($most important$)$ reason to do code reading, reviews, or inspections? Why? Rationale required.

A$.$ To count how many bugs or defects were made by other members of the team. $($This produces a good code "metric"$).$

B$.$ To learn more about OOP and data structures.

C$.$ To find code style errors such as bad names for variables or methods, incorrect indenting, etc.

D$.$ To speed up getting your code to work correctly with the other person's code

E$.$ To be sure the other person does things the way you would have done them if it was your code.
