Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Many-to-many
Why this is correct
Correct. Students and courses have a many-to-many relationship, often implemented via a junction table.
- ✗
Many-to-one
Why it's wrong here
Many-to-one is the inverse of one-to-many.
- ✗
One-to-many
Why it's wrong here
One-to-many would mean one student has many enrollments but each enrollment belongs to one student (not true for courses).
- ✗
One-to-one
Why it's wrong here
One-to-one would mean each student has exactly one enrollment.
