Final answer:
To show full details of a symmetrical object in technical drawings, normally only one view is required due to its symmetry.
Step-by-step explanation:
When depicting a symmetrical object in technical drawings, how many views are normally required to show full details of that object? Typically, one view is sufficient to represent the full details of a perfectly symmetrical object. This is because the symmetry allows all information about the shape and size of the object to be understood from a single view, whether it's the front, top, or side. Therefore, the correct answer to the question is A) One view.
