Concept:For two words to rhyme, their final stressed vowel and any following sounds must be identical.
Explanation:The given word contains the long vowel sound /uː/ at its end.
'Grew' is pronounced /ɡruː/, so it shares the exact same final vowel sound and therefore rhymes with the given word.
'Flow' and 'show' end with the diphthong /əʊ/, as in the word 'go'.
'Blur' ends with the sound /ɜː/, similar to 'her'.
None of these three words matches the /uː/ ending of the given word.
Hence, among the four choices, only 'grew' has the required rhyme.
Answer:C. grew
