Final answer:
The sentence using abbreviations properly is 'I will always remember my high school science teacher, Ms. Hennessey.' Abbreviations should be used appropriately, enclosing nonessential information in parentheses and writing out full names before using an abbreviation.
Step-by-step explanation:
The sentence that uses abbreviations appropriately is: C) I will always remember my high school science teacher, Ms. Hennessey. The sentence correctly uses the abbreviation 'Ms.' before the name of a person, which is a universally accepted abbreviation and does not require further explanation within the sentence.
When writing, it is important to use parentheses to enclose nonessential information, such as explanations or dates, that adds additional context but is not critical to the main sentence. For example, write the full name of an organization followed by the abbreviation in parentheses, which can subsequently be used alone.
Moreover, it is crucial to write out full names the first time you use them before introducing an abbreviation. Correct usage of abbreviations ensures clarity and professionalism in written communication.
