Match the following toxins (Column I) with their effects (Column II) on actin.

Column I	Column II
A. Cytochalasin D	i. Enhances nucleation by binding and stabilizing actin dimers and thereby lowering the critical concentration.
B. Latrunculin	ii. Binds at the interface between subunits in F-actin, locking adjacent subunits together and preventing actin filaments from depolymerizing.
C. Jasplakinolide	iii. Depolymerizes actin filaments by binding to the (+) end of F-actin, where it blocks further addition of subunits.
D. Phalloidin	iv. Binds and sequesters G-actin, inhibiting it from adding to a filament end.
