Final answer:
The correct answer to the question "Didn’t she get any _____ this semester?" is option d. A's, as it correctly denotes the plural form of the letter grade 'A' and is used for clarity when writing about multiple instances of the letter as a grade.
Step-by-step explanation:
The question you've asked pertains to English grammar, specifically the pluralization of letters and how to correctly represent them in writing. In English, when we make letters plural, we add an apostrophe and an 's' to the end of the letter. However, in this case, because adding an 's' alone to 'A' could create confusion as it might be read as the word 'as', we use an apostrophe for clarity.
Therefore, the correct answer to the question "Didn’t she get any _____ this semester?" is option d. A's. This represents that the student is asking about multiple instances of the grade 'A' being received.
For example, if you say, "She earned three A's this semester," it clearly signifies that 'A' is a grade, and the student received this grade three times. The apostrophe makes it easier to read and understand, especially in sentences where the meaning might otherwise be obscured.
