The correct answer is known as the pre-conscious level of awareness.
The Pre-conscious level of awareness refers to the memory or information that has already happened in the past, yet is stored inside one's memory and can be easily attained or accessed by the individual when needed. Just like in the given situation, the teacher has asked a question about my vacation and I answered that we went to Europe, so I need to cite any information about our trip to Europe so I had to access my preconscious level of awareness.
