Answer :
c) A message with an unfamiliar foreign accent
Step-by-step explanation:
The filter model of attention is based on selective attention
The filter model of attention is based on the position that stimuli is filtered and attention is selected. This is because we cannot attend to all sensory inputs at the same time hence the ability to pick out relevant information and leave the rest. An individual based on this can be able to discern a foreign accent from a speech given that he is able to filter out the relevant sounds of words that he is not accustomed to. Relevant information may be selected based on pitch, direction etc.
