What Is the Explanation for the Irrelevant Speech Effect, Assuming

What is the explanation for the irrelevant speech effect, assuming a phonological loop like that described by Baddeley's model?

A) Constantly talking during retention consumes the resources of the articulatory loop.
B) People automatically activate word meaning when they process words in working memory, thereby affecting short-term retention.
C) Additional irrelevant information consumes phonological loop resources that then cannot be dedicated to remembering the appropriate information.
D) This mechanism proposes a problem for this theory, because the theory cannot account for the effect.
