Concept:Receptive vocabulary refers to words we understand when we read or hear them, but do not actively use in our own speech or writing.
Explanation:There are two main types of vocabulary: active (productive) and passive (receptive).
Receptive vocabulary includes words that a person recognizes and understands when seeing or hearing them from others.
These words can be understood in context but are not easily recalled or used by the learner.
In contrast, productive vocabulary consists of words that are regularly and confidently used in speaking and writing.
Receptive vocabulary is larger than productive vocabulary. Learners gradually convert receptive words into productive ones.
Thus, receptive vocabulary are the words that one recognizes when he sees or hears them.
Answer:Option A: one recognizes when he sees or hears them.
