Question 5

A working student's best friend is her phone.

This sentence is correctly punctuated as it appropriately uses the possessive form "student's" to indicate that the phone belongs to the student, and it maintains a clear and grammatically correct structure.

A) Several cars' bumpers were crushed after the collision.

This option incorrectly uses the possessive form "cars'." While it suggests that the bumpers belong to multiple cars, the sentence would be clearer and more standard if it simply stated "Several bumpers of cars were crushed," avoiding confusion with the possessive.

B) Tom's and Anne's house is beautiful.

This sentence has a punctuation issue as it implies that Tom and Anne share a single house. To indicate that both have separate houses, it should be written as "Tom's house and Anne's house are beautiful," making the ownership clearer.

C) A working student's best friend is her phone.

This sentence is correctly punctuated. It uses the possessive form "student's" properly to indicate that the phone belongs to the working student, and the overall sentence structure is grammatically sound and clear.

D) The pony's saddle is so pretty.

This option is also correctly punctuated. The possessive "pony's" indicates that the saddle belongs to the pony, and the structure of the sentence adheres to grammatical conventions.

Conclusion

Option C is definitively correct as it employs proper punctuation and clarity in expressing possession. While options A, B, and D contain punctuation or structural issues, option C maintains proper grammar and effectively communicates the intended meaning. Thus, it stands out as the only fully correct choice.
