The correct answer is B. Preemptible Virtual Machines. Preemptible VMs are low-cost Compute Engine instances that cost 70-80% less than standard VMs, can be reclaimed by Google with a 30-second shutdown notice, and are ideal for fault-tolerant batch workloads.
Question
You are a program manager in a company and handling a project and you need to create a virtual machine on google cloud console that will be very simple to set up, by flipping a bit via command, API, or with developer console that gives you 30 seconds to shut down when you're preempted, allow you to save your work that also helps in the company budget upto 70-80% of less charges than the regular VMs.

Why each option
Preemptible VMs are low-cost Compute Engine instances that cost 70-80% less than standard VMs, can be reclaimed by Google with a 30-second shutdown notice, and are ideal for fault-tolerant batch workloads.
Bare Metal Solutions provide dedicated physical servers for specialized workloads like SAP HANA and do not offer preemption mechanics or the described discount pricing model.
Preemptible Virtual Machines are a specific Compute Engine instance type that Google can terminate (preempt) when capacity is needed elsewhere, providing a 30-second preemption notice via an ACPI G2 soft off signal so workloads can checkpoint state. In exchange, they are priced at 60-91% less than equivalent on-demand VMs, directly matching the scenario description of 30-second shutdown warning and 70-80% cost savings.
Standard Google Cloud VM Instances are regular on-demand VMs with no preemption behavior and no built-in 70-80% discount over themselves.
None of the above is incorrect because Preemptible Virtual Machines exactly match every characteristic described in the scenario.
