The most unbiased sampling method among the options provided would be:

**selecting assignments from a pile of collected homework at random.**

This method gives every assignment an equal chance of being selected, which reduces bias and provides a more representative sample of the entire class's understanding of the homework assignment. The other methods introduce bias by focusing on a specific group of students or assignments.
