The correct answer is related to the classification of vocabulary based on their frequency and complexity in everyday language. Tier 1 vocabulary consists of words that are commonly used in everyday speech. These are basic and fundamental words that most people are familiar with, such as "dog," "house," "happy," and "run." Because they are used frequently in daily conversations, these words contribute significantly to a young learner's basic communication skills.

In contrast, the other tiers represent different levels of vocabulary complexity and usage frequency. Tier 2 includes high-frequency words that are used more often in written texts across various contexts but may not be as familiar to all students. Tier 3 consists of specialized terms that are often discipline-specific and encountered less frequently, primarily in academic settings or certain fields, such as "photosynthesis" in biology or "peninsula" in geography. Tier 4 is not typically recognized in most vocabulary frameworks, hence the focus remains on the commonality and familiarity of Tier 1 words in everyday communication.
