The correct answer is option C i.e. all of the options
Question : Why did I choose the answer as option C
Reason : To assure it we'll match all the options with the figure
First of all in the given figure all the sides and angles are equal hence, we can refer it as regular
Secondly, It is convex because all the parts are pointing outwards and inner ones are not more than 180°
Finally, As it has 8 sides it is an octagon
Now, we can see all the three options are matching leaving C which states all of these options, hence C is correct
Extras :
1) What is Octagon ?
ans :- Octagon is an 8 sided polygon
2) What is a regular polygon ?
ans :- Any polygon which has equal angles and sides is known as a regular polygon.
3) What is convex ?
ans :- A convex is a shape where all the parts points outwards and interior angles are not more than 180°
