When you whirl a tin can in a horizontal circle overhead, the force that holds the can in the circular path acts in a direction

inward
outward
either inward or outward
parallel to gravity

When an object is in circular path then the net force on the object is always towards the center of the path

Now here the position of the tin is overhead above us

So the center of the circular path will lie just below it

So the net force is also in the direction of the center

So here we will have

Net force downwards towards the center

And this is along the direction of gravity

Now the correct answer is

parallel to gravity

i would say the answer is food.

hope this !
