Answer:
Group C; because it was semantically processed.
Step-by-step explanation:
The levels of processing model was developed by Craik and Lockhart in 1972. This model was used to evaluate the processing of memory. They modeled three levels of processing namely structural, phonetic, and semantic.
From all the levels of processing, semantic level is the deep level of processing which involves evaluation and elaboration. Semantics is a long term memory processing as it tries to evaluate the meaning.
In the given case, Group C, would be able to remember the most words because they used the semantics level of processing to learn. They would have learned those words and they reused these words in their own sentence, thus, helping them to retain more words in their memory.
