The correct answer is A. Containers.
According to CompTIA A+ Core 1 220-1201 objectives under Networking and Cloud/Virtualization Concepts:
Containers provide lightweight, portable environments that package applications and their dependencies, allowing them to run consistently across multiple environments.
Containers are ideal for development teams because they require minimal underlying infrastructure, can be quickly deployed or destroyed, and isolate applications from the host system, making it easier to manage multiple applications simultaneously.
Why the other options are incorrect:
B. IaaS (Infrastructure as a Service): Provides virtualized hardware over the cloud but is more general-purpose; it includes virtual machines, storage, and networking, not minimal isolated application environments.
C. SaaS (Software as a Service): Provides fully managed software to end-users; not intended for deploying custom web applications by a development team.
D. Desktop virtualization: Provides virtual desktop environments to users; it does not provide a minimal, disposable platform for web application development.
