ANSWER AND EXPLANATION:
The correct answer is B
Explanation: The PMBOK® Guide recognizes three types of dependencies; Mandatory, Discretionary and External. The PMBOK® Guide doesn't recognize "Internal Dependencies" as a type of dependency. Did it confuse you that one of the answers used the term "Discretional Dependencies" instead of "Discretionary Dependencies"? Expect that even on the actual PMP exam you will come across questions where terminology does not exactly match the PMBOK® Guide . Even considering that "Discretional Dependencies" is not the exact same term as “Discretionary Dependencies”, "Internal Dependencies" is even less correct and therefore the correct answer.
