Answer: A. 3 units

Step-by-step explanation:

Since the two figures are similar, that means their side lengths are proportional.

Therefore, [tex]\frac{CB}{KF} = \frac{EA}{GH}[/tex].

We are given the value for 3 of these side lengths.

Thus, [tex]\frac{10}{5} = \frac{6}{GH}[/tex].

We can cross multiply:

10 GH = 30

Divide both sides by 10:

GH = 3 units
