Which solution fits that description?

Refer to the exhibit.

A customer has the solution in the exhibit, which includes more access layer switches than are shown. Members of the customer network team mention they are considering access layer routing for a new solution to eliminate Spanning Tree Protocol (STP) and Virtual Router Redundancy protocol (VRRP). However they are concerned about meaning the routing solution. The network architect proposes a solution that eliminates STP and VRRP without requiring routing at the access layer, although the solution can use access layer routing.

Which solution fits that description?
A . Two HP 10500 Series, using intelligent Resilient Framework (IRF) at the core, HP S400 zl Series switches at the access layer
B . Two HP 10500 Series switches, using Hot Standby Router Protocol (HSRP), at the core. HP 2600 Series switch at the access layer
C . Two HP 8200 zl Series switches, using distributed Trunking, at the core. HP 5400 zl Series switches at the access layer
D . Two HP zl Series switches, using backplane stacking, at the core. HP 5400 zl Series switches, using the backbone stacking at the access layer
