Which sentence demonstrates the correct use of quotation marks?

The choice that demonstrates the correct use of quotation marks is the one where the phrase "glass ceiling" is enclosed in quotation marks to indicate that it is a specific term or phrase being referenced. In this context, quotation marks are used appropriately to highlight a concept that is frequently discussed in relation to barriers faced by women in the workplace.

In contrast, the other choices do not adhere to standard punctuation rules. The second option features a proper quote but lacks a closing punctuation mark after "store." The third option also has a similar issue; it does not end with the necessary punctuation, which makes it an incorrect sentence structure. The fourth choice fails altogether by not placing the spoken words in quotation marks, which is essential for indicating dialogue or speech.
