Final answer:
The sentence with incorrect apostrophe usage in the given options is 'What did you do with the houseplant's I bought yesterday?' The apostrophe is misused, as the word should be the plural 'houseplants' and not the possessive form.
Step-by-step explanation:
Identifying Apostrophe Errors
When evaluating sentences for proper apostrophe usage, it's crucial to understand that an apostrophe has two main functions: to indicate possession and to form contractions. Apostrophe errors often involve using an apostrophe for plurals or omitting it where it signals possession or a contraction.
Incorrect Apostrophe Usage
Among the given options, the sentence with an error in apostrophe usage is: What did you do with the houseplant's I bought yesterday? The correct option should not use an apostrophe, as the word 'houseplants' is meant to be a plural noun, not a possessive one. The correct sentence should be: What did you do with the houseplants I bought yesterday?
Proper Apostrophe Usage in Possessives and Contractions
When using apostrophes to show possession, you add an apostrophe and 's' to a singular noun, for example, the dog's leash. For a plural noun that already ends with an 's', you place the apostrophe after the final 's', like the cats' owner. In the case of contractions, the apostrophe stands in place of the omitted letter(s), such as it's for it is or you're for you are.
Returning to the multiple-choice question, the sentence with incorrect apostrophe usage is: a. What did you do with the houseplant's I bought yesterday?, which should not have an apostrophe in 'houseplants'.
