Match the following proteins (Column I) with their function (Column II). Which of the following is correct?

Column I	Column II
a. Profilin	i. binds to the (+) end of an actin filament, thereby inhibiting subunit addition or loss.
b. Cofilin	ii. blocks (−) ends, inhibits filament disassembly, to stabilize filaments
c. Thymosin-β4	iii. involved in actin treadmilling, but it binds specifically to F-actin in which the subunits contain ADP
d. Cap Z	iv. binds ADP–G-actin and catalyzes the exchange of ADP for ATP
e. Tropomodulin	v. binds to ATP–G-actin in such a way that it inhibits addition of the actin subunit to either end of the filament.
