Final Answer:
The folds pictured in the image are classified as synclines. Option B is answer.
Step-by-step explanation:
Synclines Definition: Synclines are geological structures characterized by downward-folding rock layers, creating a trough-like shape. In a syncline, the youngest rock layers are found in the center of the fold, while progressively older layers surround them.
Anticlines Comparison: Anticlines, in contrast, are folds where rock layers arch upward, with the oldest layers positioned at the crest of the fold.
Recognition of Synclines: The folds in the image exhibit a trough configuration, indicating a concave shape. This aligns with the characteristic structure of synclines, making option B (synclines) the appropriate identification.
Therefore, option B (synclines) is the correct answer for the given geological folds.
