I am unable to choose std B2s type for nodes while creating aks cluster

Please max sure you select 2 nodes for the pool. Please follow this guide exactly to create an AKS Cluster in the Azure Playground:

@al1 I still face while choosing the size B4ms is there any chance I can get an update on it, I can create a cluster with a different size but we need b4ms as we already have a cluster with that size and creating this cluster for disaster recovery/backup.
