Answer:
Memory recovery stage.
Step-by-step explanation:
Long-term memory is the ability to keep recent information from a few days ago to decades. This type of memory is divided into three phases: acquisition, storage and recovery.
The so-called recovery phase is about remembering or trying to remember. It occurs when gray matter is searched for information scattered throughout the cortex.
Since Jiao is trying to remember where she kept the birthday gift receipt she bought for her mother, we can conclude that it is in the memory recovery stage.
