A customer has a DMX3000 at their headquarters (Site X). They currently run two applications on the DMX3000, both of which need to be replicated for DR purposes. The first application needs to be replicated to Site Y, which is 32 kilometers away. The second application needs to be mirrored at a different site, Site Z, which is 26 kilometers away.
At a minimum, which additional Symmetrix and remote director hardware is required to implement the solution?

A.
Three DMXs, one each at Sites X, Y and Z three pairs of fiber adapters, one pair for each DMX

B.
Two DMXs, one each at Sites Y and Z three pairs of fiber adapters, one each at Sites X, Y, and Z

C.
Two DMXs, one each at Sites Y and Z two pairs of fiber adapters, one each at Sites Y and Z

D.
Two DMXs, one each at Y and Z four pairs of fiber adapters, two pairs at Z and one each at Sites Y and X
