Answer: The ∆ABC has been transformed to yield ∆A'B'C'. The fourth diagram shows that the transformation could NOT be achieved by rotation alone.

Explanation:

In first figure ∆ABC has been transformed to yield ∆A'B'C' by rotation of 180 degree either clockwise or counterclockwise along the midpoint of AB.

The second and third figure are same. In both figures ∆ABC has been transformed to yield ∆A'B'C' by rotation of 180 degree either clockwise or counterclockwise along the origin.

In fourth figure ∆ABC has been transformed to yield ∆A'B'C' by rotation of 180 degree either clockwise or counterclockwise along the origin.

But only in fourth figure ∆ABC has been transformed to yield ∆A'B'C' by reflection along the x-axis.

Therefore, the correct option is 4th diagram.
