Answer: The correct option is A: Encoding.
Step-by-step explanation:
Encoding or memory encoding is the very first step in the process of creating a new memory. This process allows the brain to store perceived objects, sensorial experiences, or any daily life situation and be able to recall them later from short-term or long-term memory. The encoding process may occurs in the following sequence:
- Perception (through the senses).
 - Attention (understand what is going on).
 - Emotion (reacting to what is happening).
 - Creating a new memory.
