In a cluster with 3 servers, the default disk layout is 3-way mirror. That means a 3TB increase should cost you 9TB footprint increase, or 3TB per node. If you just add 3TB hard drive, you won't get an additional 3TB in your S2D volume.

Correct answer is B. https://docs.microsoft.com/en-us/windows-server/storage/storage-spaces/resize-volumes Capacity in the storage pool Before you resize a volume, make sure you have enough capacity in the storage pool to accommodate its new, larger footprint. For example, when resizing a three-way mirror volume from 1 TB to 2 TB, its footprint would grow from 3 TB to 6 TB. For the resize to succeed, you would need at least (6 - 3) = 3 TB of available capacity in the storage pool.

I guess correct answer is B. https://docs.microsoft.com/en-us/windows-server/storage/storage-spaces/drive-symmetry-considerations "Same drive sizes in every serve: Recommended" So, if extend by 3TB, all other nodes can have additional 3TB.
