An enterprise customer cannot tolerate any data loss. They currently use multihop SRDF/AR to protect their data. Production Site A is 32 kilometers from the middle or Bunker Site B. The Disaster Recovery (DR) Site C is 2,000 kilometers away.
The customer has asked you to review their design so that in the event of a single site disaster they can still maintain remote disaster protection with minimal synchronization time.
Which solution do you recommend?

A.
1. Use SRDF/AR between A and B and SRDF/S between B and C.
2. In the event of a data center failure, create an SRDF/A connection between the two remaining sites.

B.
1. Use SRDF/AR between A and B.
2. Use SRDF/DM between B and C.
3. If one of the sites fails, establish an SRDF/A connection between the two remaining sites.

C.
1. Use SRDF/AR between A and B.
2. Use SRDF/DM between B and C.
3. If one of the sites fails, establish an SRDF/A connection between the two remaining sites.

D.
1. Use SRDF/Star between the three sites.
2. If C fails, continue to run SRDF/S between A and B.
3. If one of the other two sites fails, continue with SRDF/A between the two remaining sites.
