Final answer:
Double dissociation observed in Clive Wearing, H.M., and K.F. shows memory and language operate independently and are affected by brain damage separately, highlighting these functions are supported by different neural structures.Hence, the correct answer is option B.
Step-by-step explanation:
The concept of double dissociation is observed in the cases of Clive Wearing and H.M. versus K.F., demonstrating the independence between memory and language. Clive Wearing and H.M. suffered from severe anterograde amnesia yet retained their language abilities, while K.F. had impaired short-term memory for verbal information but normal functioning in other cognitive domains. This indicates that memory and language are supported by different neural structures and can be independently affected by brain damage.
