Answer:

Explanation:
Homophones are those words that have the same sound and pronunciations but differ in their spellings, origins and most importantly their meanings. Examples of homophones are- bed/ bad, know/ no, dear/ deer etc.
For the sentence -
They showed us ________ finished projects at the end of class,
the homophone to be used will be "their". It sounds the same with the word 'dear' but have different connotations. Also, "their" is the possessive form of the pronoun 'they'.
Thus, the final sentence will be
They showed us their finished projects at the end of class.
