Centrifugal and centripetal force

[Noziroh]

There is a grass planted in a container which spins.
Will the grass grow from the center of the container or will it bend towards the center.
These are provided answers:

This is a question in my book and there it is stated that it will bend towards the center(A answer) but it is not explained why.

I would appreciate any help, thanks :D

In theory, grass tries to grow along the direction of force, as this is the most stable configuration. That leads to "a".
In reality, grass can grow or bend in other directions, too, especially if it does not exceed a height of a few cm.
