Question

1. which two-dimensional views are standard in an orthographic drawing?

front, left side, top
top, left side, bottom
front, right side, top
front, right side, left side

Explanation:

In orthographic drawing, the standard two - dimensional views are the front view, the right - side view, and the top view. The first option has left - side view which is not standard in the typical orthographic projection (third - angle projection which is common in many engineering contexts uses front, right - side, and top). The second option with bottom view is not standard. The fourth option with left and right side along with front is not the standard set of three views. So the correct option is the one with front, right side, top.

Answer:

C. front, right side, top (assuming the third option is labeled as C; if the original options have different labels, adjust the label according to the original, but the text should be "front, right side, top")
