Concept:
- In a top (plan) view, only the horizontal position of every point matters; height above the ground is invisible. A handle that arches straight up and back down still appears as a straight line from above, as long as it never swings sideways.
- Only a connector that bends out of the vertical plane containing the two bases will show up as a curved or offset line in the top view.
Step 1: Read what image P actually fixes.
Image P is a straight bar joining two circles. This fixes only the plan positions of the two cup rims and the connector between them; it says nothing about how high the connector arches.
Step 2: Trace the horizontal footprint of the handle in each option.
In options A, B, and C, the connecting handle rises and falls entirely within the vertical plane that passes through both cup centres. It never swings out to the left or right of that line.
Step 3: Project each traced footprint onto the ground.
Since the handles in A, B, and C stay directly above the straight line joining the two cup centres, their top view collapses to a single straight segment between the two circles, exactly matching image P.
Step 4: Check option D for a sideways deviation.
In option D, the handle bends sideways as well as vertically, so its horizontal footprint is not a straight line between the two centres but a bent or offset path. Viewed from above, this produces a kinked line, not the plain straight bar shown in P.
Final Answer: A, B, and C
