Identify the figure given in the options which when put in place of the question mark (?) will logically complete the series?

- (a)

- (b)

- (c)

- (d)

Answer
Why
Correct — A. Each box holds four symbols, one per corner: a circle on a stalk, a down arrow, a filled triangle on a stalk and an open arc on a stalk.
Rule: every symbol moves one corner per step and no symbol ever turns. The circle and the arc travel anticlockwise, the arrow and the triangle clockwise.
Follow the circle: top-left, bottom-left, bottom-right, top-right. A one-corner step closes after four moves, so every symbol is back where it started and the fifth box repeats the first.
Option (a) is that box — circle top-left, arrow top-right, triangle bottom-left, arc bottom-right, each drawn facing exactly as in figure 1.
Why the others are wrong
- (b)Right corners, wrong symbols. The circle, triangle and arc are all mirrored — the stalk sits on the far side and the triangle points left. Nothing in the series flips.
- (c)Option (c) puts the arrow at the top-left, but that corner belongs to the circle, which has just completed its loop back to where it began.
- (d)Option (d) is figure 3 over again — arc top-left, triangle top-right, arrow bottom-left, circle bottom-right. The fifth box has to match figure 1.
Concept
Positional series items ask you to track objects, not to read the picture whole. Name each symbol, write down the corner it occupies in each box, then read the step off your own list.
Two things move independently: the corner a symbol occupies, and its own orientation. Here the orientation never changes, which is what rules out the mirrored option, while the corner changes by exactly one step with two symbols running each way round.
Because the loop closes after four steps, the answer is figure 1 again. That feels wrong to candidates who expect a fresh picture, and one of the options offers a repeat of figure 3 instead.
Key facts
- Each symbol advances one corner per figure and keeps its own orientation throughout.
- The circle and the arc run anticlockwise while the arrow and the triangle run clockwise.
- A one-corner step repeats after four moves, so the fifth figure equals the first.

Common traps
- Accepting a mirrored symbol because it stands in the right corner
- Assuming the whole figure rotates when the symbols move independently
- Missing that the cycle has closed and picking a later figure of the series
