Answer:

A. Enlargement, 1.5

Step-by-step explanation:

Comparing the two triangles, it would be observed that ΔD'E'F' is larger than ΔDEF. This implies that ΔDEF has been multiplied by a scale factor.

To determine the scale factor used, consider the side DE and D'E' of the two triangles:

scale factor = \frac{D'E'}{DE}

                   = \frac{6}{4}

scale factor  = 1.5

Therefore, ΔDEF was enlarged to ΔD'E'F' using a scale factor of 1.5. Then the correct option is A.
