Answer:
D) It appeared as though Mrs. Hale was answering the question, but she actually meant something quite different with her response.
Explanation:
In Susan Glaspell's play "Triffles," the people investigating the crime find sewing elements which the men overlook because they believe a kitchen holds trivial items. The reason is that the thoughts and opinions of women were not considered important at the time. Thus, the uneven stitching in Mrs. Wright's quilt indicates that she was upset or distracted by disturbed during her quilting. As a result, with the discovery of the dead bird, the women realize that Mrs Wright had was going through an oppressive marriage and had reasons to kill her husband. That is why Mrs. Hale means something different than what she is answering: the women are actually hiding the evidence to protect Mrs. Wright.
The best correction of the clause fragment is to C. delete the word "although."
Without that word, you get a proper single independent sentence, and not a fragment.
