Which of the following is a sensitive fragment?

A. The first tiny purple crocuses bloomed in February
B. High up in the willow tree in the springtime
C. Covered in snow, the branches reflected the sunlight

C. Covered in snow, the branches reflected the sunlight

Based on the given fragments, it appears that option C is the sensitive fragment.

To determine which of the following fragments is a sensitive fragment, it's necessary to understand what a sensitive fragment is. A sensitive fragment is a group of words that lacks a subject, a predicate, or both, making it incomplete or lacking a meaningful sentence structure.

Out of the three options given:

A. "The first tiny purple crocuses bloomed in February" has a subject ("the first tiny purple crocuses") and a predicate ("bloomed in February"). This is a complete sentence and not a sensitive fragment.

B. "High up in the willow tree in the springtime" lacks a subject and a predicate. Although it has some descriptive words, it does not form a complete sentence. Therefore, this is a sensitive fragment.

C. "Covered in snow, the branches reflected the sunlight" has a subject ("the branches") and a predicate ("reflected the sunlight"). This is a complete sentence and not a sensitive fragment.

So, the sensitive fragment is option B, "High up in the willow tree in the springtime."
