Explanation

The CISO's key constraints are: (1) reduce operating costs, (2) all resources must be dedicated, and (3) managing a private cloud is not an option. Single-tenancy SaaS (C) best satisfies constraint 2 - the infrastructure is dedicated solely to one customer/tenant, so resources are not shared. Community cloud (A) involves shared infrastructure among a group of organizations with common interests - resources are not truly dedicated to one company, violating constraint 2. Multitenant SaaS (B) explicitly shares resources across many customers. On-premises (D) is not a cloud solution and contradicts the vendor-managed requirement. While single-tenancy is more expensive than multitenant, it is the only option that meets the 'dedicated resources, externally managed' requirement. Note: some exam keys favor Community cloud here if 'dedicated to the community' is the interpretation used.
