Answer:
c. Along the narrow forest trail, ferns and tiny wildflowers grew.
Step-by-step explanation:
Phrase fragments are constructions that are wrong because they are standing alone as if they were full sentences when in reality, they are not sentences because they do not express complete thoughts on their own. One way to correct them is to make place them within a sentence so that they can make sense. In sentence C, the phrase “Along the narrow forest trail” is correctly set because it is within a sentence, adding more detail to the independent clause “ferns and tiny wildflowers grew.”
