**Core Concept**
Explicit memory, also known as declarative memory, is a type of long-term memory that involves the conscious recollection of factual information, past events, and learned skills. It is a voluntary memory system that requires intentional recall.

**Why the Correct Answer is Right**
Explicit memory involves the encoding, storage, and retrieval of information in a conscious and intentional manner. It is responsible for remembering specific details, such as a person's name, a past event, or a learned skill. This type of memory is mediated by the hippocampus and the prefrontal cortex, which are regions of the brain involved in attention, perception, and working memory.

**Why Each Wrong Option is Incorrect**
**Option A:** Implicit memory, also known as procedural memory, is a type of long-term memory that involves the unconscious recollection of skills and habits, such as riding a bike or tying shoelaces. It is not explicit memory.

**Option B:** Sensory memory is a type of short-term memory that involves the brief storage of sensory information, such as visual or auditory information. It is not a type of explicit memory.

**Option C:** Working memory is a type of short-term memory that involves the temporary storage and manipulation of information, such as holding a phone number in mind while dialing. It is not a type of explicit memory.

**Clinical Pearl / High-Yield Fact**
One key difference between explicit and implicit memory is that explicit memory requires conscious recall, while implicit memory involves automatic recall. For example, a person with amnesia may be able to recall their name and address (explicit memory), but may still be able to ride a bike (implicit memory).

**Correct Answer: C. Sensory memory is a type of short-term memory that involves the brief storage of sensory information, such as visual or auditory information.
