Step-by-step explanation:
The parascapular spines of a thyreophoran dinosaur would be found next to the shoulder (Option C). The term "thyreophoran" refers to a group of armored dinosaurs that includes stegosaurs and ankylosaurs. These dinosaurs are known for having bony plates or spines along their backs and flanks. The parascapular spines would be located near the shoulder region, potentially as part of the protective armor arrangement or as a display feature.
