Final answer:
The pair 'Convention' and 'Conversion' is an example of a perfect rhyme on a multisyllabic word, as both share identical stressed syllables and ending sounds, thereby fully meeting the criteria for perfect rhyming. The correct answer is option: D. Convention, conversion.
Step-by-step explanation:
An example of a perfect rhyme on a multisyllabic word is given by the pair 'Convention' and 'Conversion'. In perfect rhyme, the stressed syllables of the ending must sound exactly the same following the consonant that comes right before the stressed syllable. Both words must use the same letters in spelling to make the same sounds.
Therefore, 'Convention' and 'Conversion' meet this criteria as they share identical stressed syllables from the 'ven' onward, making them perfect rhymes.
- 'Sender' and 'lender', while they do rhyme, are not multisyllabic.
- 'Ocean' and 'portion' are multisyllabic but do not share a perfect rhyme due to different vowel sounds and final consonants.
- 'Capsize' and 'riptide' have differing vowel sounds and different endings, and thus do not form a perfect rhyme.
