Question

rotation, then translation
rotation, then reflection
reflection, then rotation
reflection, then translation

Explanation:

To transform one shape to another, we analyze the possible sequence of geometric transformations. If we first rotate a shape, we change its orientation. Then, if we translate it, we move it to a new position without changing its size, shape or orientation further. Looking at the figures, we can see that a rotation to change the orientation and then a translation to move it to the final position is a likely sequence. A reflection would flip the shape across a line which doesn't seem to be the case here based on the orientation and position of the shapes.

Answer:

rotation, then translation
