The correct sentence is "Gina's mom was disappointed upon learning Gina received seventy-eight percent on her math test." Here option A is correct.
In this sentence, the possessive form of "Gina's" is correctly written with an apostrophe, and the hyphen is used correctly in "seventy-eight percent" to connect the words and form a compound number. Proper punctuation is crucial for clarity and correctness in written communication.
Option B is incorrect because it uses a plural form, "Ginas'," which is not appropriate in this context. Option C is incorrect because it lacks a hyphen in "seventy eight percent," making it less clear and accurate.
Option D is incorrect because it combines the words "seventy" and "eight" without a hyphen, resulting in a lack of clarity in expressing the compound number. Here option A is correct.
