C.

By mid-September, Terri will be Jennifer's mother-in-law.

The sentence that uses hyphens correctly is:

C. By mid-September, Terri will be Jennifer's mother-in-law.

The sentence that uses hyphens correctly is option C: "By mid-September, Terri will be Jennifer's mother-in-law."

To explain why this sentence is correct, let's first understand the purpose of hyphens. Hyphens are used to join words together to create compound words or to clarify the relationships between words.

In option A, "She was a good-student but she failed to turn in her work," the hyphen is not used correctly. It should be replaced with a space because "good" and "student" are not forming a compound word.

In option B, "He left-without giving any notice at all," the hyphen is used to connect two words, "left" and "without," and suggests a single idea of leaving without giving notice. However, this sentence would be better written without a hyphen, such as "He left without giving any notice at all."

In option D, "Please call my lawyer-Jessica Chang-for answers to your questions," the hyphen is used incorrectly. To indicate the connection between "lawyer" and "Jessica Chang," an em dash (—) or a hyphen with spaces before and after it should be used. For example, "Please call my lawyer — Jessica Chang — for answers to your questions" or "Please call my lawyer - Jessica Chang - for answers to your questions."

Therefore, the sentence that uses hyphens correctly is option C: "By mid-September, Terri will be Jennifer's mother-in-law." The hyphen in "mother-in-law" is used appropriately to connect the compound word and clarify the relationship between "mother" and "law."
