What will most likely happen when a component is removed from a reaction system at equilibrium?

The system will be unaffected by stress.
The addition of a catalyst will change the equilibrium.
The equilibrium system will shift to remove more of what was removed.
The equilibrium system will shift to replace some of what was removed.

off the bat, you can eliminate the first two (systems *are* affected by stress as you can see w/ le chatelier's principle. additionally, catalysts don't change equilibrium positions, they simply allow rxns to reach equilbrium faster)

between the last two, which one is in accordance w/ le chatelier's principle?

thank you i had no idea how to say that to him

The equilibrium will shift to produce more of that species to restore balance 
So with saying that the last option
 The equilibrium system will shift to replace some of what was removed.
