Similar question was on my test that I passed Nov 20 2021. Question had HPC keyword and one of the alternatives were "select the group as cluster placement". I went with it.

While A is indeed correct, what about dedicated instance? I guess the instances may be placed on different servers owned by us(we have no control on placement,unlike dedicated host).

A Link: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/placement-groups.html Summary: Cluster – packs instances close together inside an Availability Zone. This strategy enables workloads to achieve the low-latency network performance necessary for tightly-coupled node-to-node communication that is typical of HPC applications.
