Select the option that indicates the correct arrangement of the following words in a logical and meaningful order.
1. Square
2. Hexagon
3. Heptagon
4. Triangle
5. Pentagon

Logic: Number of sides in increasing order:

Triangle (3 sides) → Square (4 sides) → Pentagon (5 sides) → Hexagon (6 sides) → Heptagon (7 sides)​​

So sequence will be:  4, 1, 5, 2, 3.

Thus, correct option is (a).
