Which of the following is a phase of vocabulary development?

The correct answer is A, Partial Alphabetic Phase. During the Partial Alphabetic Phase of vocabulary development, children begin to recognize some letters and make connections between those letters and the sounds they represent. They may also recognize some high-frequency words by sight. This phase is an early stage of literacy development where children are just beginning to understand the alphabetic principle.

Options B, C, and D are related to stages of spelling development rather than vocabulary development. Interactive Alphabetic Phase, Analytical Alphabetic Phase, and Experimental Alphabetic Phase refer to stages where children are developing their understanding of how letters represent sounds and how words are formed using these letter-sound correspondences.
