rectangle
Explanation
According to Euler's characteristics all platonic solids are like a sphere.
All Platonic Solids are like a Sphere, we can reshape them so that they become a Sphere (move their corner points, then curve their faces a bit).
For this reason we know that $$F + V - E = 2$$ for a sphere.

0%
$$2$$
0%
$$1$$
0%
$$0$$
Explanation
Given:-
$$F=n$$
$$E =n+1$$
As per the Euler's formula,
$$F-E+V=2$$
$$\Rightarrow n-(n+1)+V=2$$
$$\Rightarrow n-n-1+V=2$$
$$\Rightarrow V=3 $$
Hence, option $$A$$ is correct.
