Answer: B

Explanation:

Shared Risk Link Group (SRLG) -disjoint―Eliminates LF As that belong to any of the protected path SRLGs. SRLGs refer to situations where links in a network share a common fiber (or a common physical attribute). If one link fails, other links in the group may also fail. Therefore, links in a group share risks.
