Can a reg.dealer charge gst if purchase from composition dlr

Can a registered dealer charge GST from customers on goods purchased from registered composition dealer? For e.g.: Mr A (Composition Dealer) sells goods to Mr.B (Registered Dealer not under Composition) (NOTE: Mr. A did not charge GST from Mr.B. as Mr. A is a composition dealer). Now Mr. B sells these goods to Mr. C (Registered Dealer). So in this case should Mr. B charge GST on goods sold to Mr. C?
