Final answer:
Option b, 'buy', ends with the same long "i" sound as the word 'rye'. Words like tray, tree, and lay have different ending sounds and do not match the sound of 'rye'.
Step-by-step explanation:
The question asks which word ends with the same sound as the word rye. To determine the correct answer, we need to identify the ending sound of rye, which is a long "i" sound, phonetically represented as /aɪ/.
Out of the options provided, buy (option b) is the word that ends with the same sound as rye, as both words have the long "i" sound at the end. This sound is represented with different letters in these words, but they sound the same when spoken.
Words like tray, tree, and lay do not end with this sound. Tray ends with the sound /eɪ/, tree with /i:/, and lay with /eɪ/ as well, which are different from the /aɪ/ sound in rye. Therefore, option b, buy, is the correct answer to the question posed by the student.
