Explanation:

Mental symbols refer to the use of symbols such as sound, words, mental images, etc. to represent reality or any element of it such as an object, situation, etc. This allows individuals to represent objects that are not present or do not exist in reality, also this is an important stage in the children development and essential for language development. According to this, the infant using mental symbols is "Peter, who is saying "v!" and moving his hand like a car" because he is using a sound (symbol) to represent reality and an object he knows but is not present.
