The most unbiased sampling method would be **selecting assignments from a pile of collected homework at random**. This method ensures that every assignment has an equal chance of being selected, making it the most representative of the entire group of students' work. The other methods introduce biases based on specific criteria that do not reflect the overall performance or understanding of all students.
