The correct answer identifies Infrastructure as a Service (IaaS) as the type of cloud service where the customer bears more responsibility for incident response. This is due to the fundamental way in which IaaS operates, providing customers with virtualized computing resources over the internet. Users have significant control over the operating systems, applications, and data hosted on the infrastructure, which enables greater flexibility but also includes the responsibility for securing and managing those components.

In IaaS, while the cloud provider is responsible for the physical infrastructure, networking, and storage, customers must handle the implementation of security measures, system updates, configurations, monitoring, and incident response related to their own environments. This includes managing virtual machines, ensuring that security patches are applied, and being adequately prepared to respond to incidents that may occur on their deployed systems.

In contrast, other service models, such as Platform as a Service (PaaS) and Software as a Service (SaaS), provide higher levels of abstraction and management from the provider's side. In PaaS, users still maintain some control over applications and data but do not have to manage the underlying hardware and software layers to the same extent as in IaaS. In SaaS, the provider typically takes full responsibility
