What is the collapsed layer in collapsed core architectures?
In a collapsed core architecture, the core and distribution layers are combined into a single layer. This combines the functions of the core and distribution layers while the access layer remains separate. This architecture is commonly implemented in smaller networks where having a separate core and distribution layer is unnecessary and can be combined to simplify the network design.
Answer A Correct https://www.juniper.net/documentation/en_US/release-independent/nce/topics/concept/nce-182-evpn-collapsed-core-evpn-multihoming-campus-overview.html#:~:text=A%20collapsed%20core%20architecture%20takes,layer%20on%20a%20single%20switch. A collapsed core architecture takes the normal three-tier hierarchical network and collapses it into a two-tier network. In a two-tier network, the function of the switches in the core layer and distribution layer are “collapsed” into a combined core and distribution layer on a single switch.
If you choose a hierarchical tiered architecture, the exact number of tiers that you would implement in a network depends on the characteristics of the deployment site. For example, a site that occupies a single building might only require two layers while a larger campus of multiple buildings will most likely require three layers. In smaller networks, core and distribution layers are combined and the resulting architecture is called a collapsed core architecture.

All are Wrong. In fact, in colapsed core there are no "distribution". Only core and acess layer
A is correct
