How many moments of inertia can an object have? An object can have three moments

Question

How many moments of inertia can an object have?

An object can have three moments of inertia, one each for the x-, y-, and z-axes.
or
There are an infinite number of moments of inertia for an object. The moment of inertia depends on an object?s size, shape, mass, mass distribution, and the axis of rotation. Since there are an infinite number of axes of rotation, there are an infinite number of moments of inertia.
or
There are an infinite number of moments of inertia for an object. The random nature of measurement will always produce different values; hence there are an infinite number of moments of inertia.
or
Forty-two.
or
One. The moment of inertia is the rotational mass. Since an object only has one mass, it can only have one moment of inertia.
or
There are an infinite number of moments of inertia for an object. The moment of inertia depends on an object?s size, shape, mass, mass distribution, and the number of lines through the object. Since there are an infinite number of lines through an object, there are infinite moments of inertia.
or
There are eleven possible moments of inertia for an object. The latest string theories posit eleven dimensions in the universe, so this is has to be the number of moments of inertia.
or
There are an infinite number of moments of inertia for an object. Any real-world object has an infinite number of points in it, therefore there are an infinite number of moments of inertia.
