Triangle abc is translated by the rule (x + 1, y + 1) and then dilated by a scale factor of 2 centered at the origin. which statement describes the properties of triangles abc and a''b''c'' after the transformations?

a) ∠c and ∠c'' are congruent after both the translation and the dilation.
b) ∠c and ∠c'' are congruent after the dilation, but not after the translation.
c) segment ac and segment a double prime c double prime are congruent after both the translation and the dilation.
d) segment ac and segment a double prime c double prime are congruent after the dilation, but not after the translation.
