Option 3 :

The logic is as follows;

Sides in the Outer figure are one less than the sides in the inner figure.

**1) In Option 1:**

Outer Figure = Triangle

Outer Figure Sides = 3

Inner Figure = Square

Inner Figure Sides = 4

2) In Option 2:

Outer Figure = Hexagon

Outer Figure Sides = 6

Inner Figure = Heptagon

Inner Figure Sides = 7

**3) **In Option 3:

Outer Figure = Hexagon

Outer Figure Sides = 6

Outer Figure = Pentagon

Inner Figure Sides = 5

In this figure side of the Outer Figure is one more than the sides of the inner figure.

**4) **In Option 4:

Outer Figure = Square

Outer Figure Sides = 4

Outer Figure = Pentagon

Inner Figure Sides = 5

Hence, option (3) is the correct answer.

Side of polygons and their name:

Polygon | Number of Sides | Figure |

Triangle | 3 | |

Square | 4 | |

Pentagon | 5 | |

Hexagon | 6 | |

Heptagon | 7 | |

Octagon | 8 | |

Nonagon | 9 | |

Decagon | 10 |
