Four metals labelled as A, B, C and D. They react with each other and with acids in the following way:
 (1) B displaces only C from the solution
(2) Only A and D displace hydrogen from 1M HCl
(3) None of the metals displace D from its solution .
Arrange the metals along with hydrogen in the decreasing order of their reduction potential values.
