Mandatory dependencies represent dependencies that cannot be changed. These dependencies are inherent to the nature of the project activities and must be completed in a specific order. They are often related to technical limitations, contractual obligations, or even physical constraints. As such, they are not optional or flexible and must be adhered to for the successful completion of the project.

Options B, C, and D are incorrect because:

- Option B, external factors affecting the project, refers to dependencies that are outside the control of the project team, not dependencies that cannot be changed.

- Option C, internal relationships within the project, while important, do not specifically refer to dependencies that cannot be changed.

- Option D, options for different activity orders, suggests flexibility in sequencing activities, which is contrary to the concept of mandatory dependencies where the sequence is fixed and must be followed.
