b. memory decay.
c. retrograde amnesia.
d. the tip-of-the-tongue phenomenon.

d. the tip-of-the-tongue phenomenon.

Explanation:

Tip-of-the-tongue phenomenon: The term tip-of-the-tongue phenomenon is also referred to as TOT, and is described as the process of a person to fail in retrieving a specific term or word from the memory, along with the partial recall and feeling of retrieval being imminent.

In other words, the tip-of-the-tongue phenomenon is a person's subjective feeling of being confident enough to know a particular piece of information instead of not able to recall the word correctly. Hence the person can recall a similar word from the memory yet not the exact word or information.

In the question above, Mickey is experiencing the tip-of-the-tongue phenomenon.

the density would be a smaller number.
