Final answer:
The Visigoths and Angles adopted elements of Roman culture through a process of acculturation, which included emulating Roman institutions and blending cultural traditions.
Step-by-step explanation:
After migrating to Roman lands, the Visigoths and Angles underwent a process of acculturation, blending cultural traditions with those of the Roman populations they conquered. This resulted in the adoption of Roman culture and institutions to some extent. The Visigoths, in particular, attempted to emulate Roman institutions in Spain by creating written law codes. However, their relationship with their Hispano-Roman subjects was uneasy, and they generally remained apart from them. The Angles, part of the group known as Anglo-Saxons, also settled in Roman territories such as Britain and over time assimilated with the local culture. The best answer to the question is (A) Adopted Roman culture, as both the Visigoths and the Angles adopted cultural elements of the Romans despite their political dominance and conflicts.
