Question

select all the cones.

Explanation:

A cone is a three - dimensional geometric shape with a circular base and a single vertex (apex) connected to the base by a curved surface. The first figure is a rectangular prism (a box - like shape) with six rectangular faces, so it's not a cone. The second figure has a circular base and a pointed apex with a curved surface connecting them, so it's a cone. The third figure also has a circular base and a pointed apex with a curved surface, so it's a cone. The fourth figure has a circular base and a pointed apex (even though it looks a bit "flatter" on the side, it still has the basic cone structure with a circular base and an apex connected by a curved surface), so it's a cone.

Answer:

The second (green), third (yellow), and fourth (purple) figures are cones. So we select the second, third, and fourth options (assuming the figures are in order from left to right as first: orange rectangular prism, second: green cone, third: yellow cone, fourth: purple cone).
