Concept:Short-term memory is a temporary storage system that retains information for a limited time, typically 20–30 seconds.
Explanation:Human memory has different types. Short-term memory holds a limited amount of information for a short duration, often around 20–30 seconds.
If you do not actively rehearse or transfer it, the information fades quickly.
Long-term memory stores information for hours to years, not seconds.
Active memory is not a standard classification in memory models.
Rote memory refers to memorization by repetition, not a specific time span.
Therefore, the correct option is short-term memory.
Answer:B. Short term memory
