Group the given figures onto three classes using each figure only once.
| D | E | N | U | W | H | B | M | A |
| (a) | (b) | (c) | (d) | (e) | (f) | (g) | (h) | (i) |
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → (a, d, g); (b, e, h); (c, f, i)
The letters are grouped by the lines they are made of: curved lines, or the number of straight lines.
(a, d, g) D, U, B — each has a curved part.
(b, e, h) E, W, M — each is made of four straight lines.
(c, f, i) N, H, A — each is made of three straight lines.
Each letter is used once and the three groups follow one rule, which no other option does: Option (1) puts N with E and W, Option (3) mixes D, E and N in one group, and Option (4) uses (c) twice.
