Which statement is true about all cylinders

Answer:
Option 3rd is the right answer.
Step-by-step explanation:
Lets check the given statements.
1)The height is a vertical distance - The height of the cylinder is the perpendicular distance between both the bases of the cylinder.
2)The diameter of a base is less than the height - Both the diameter and height can be equal. Its not always true that the diameter is less than height.
3)The radii of both bases are the same - Both the bases will have the same radius in any cylinder.
4)The area of a base is greater than 1 square unit - This is not justifiable.
So, only option 3 is the true statement here.
