Answer:
Option B. similar
Explanation:
When a figure is dilated by a coefficient or scale the sides of the dilated figure will be changed.
Length of the sides will be changed but the angles will remain same.
As we know two triangles will be similar but not congruent because there is no property of AAA for the congruence. So option A is not true.
and for dilated image angles will remain same so option C and D are also not true.
Therefore Option B is the correct option.
