Site Reliability Engineers concentrate on operational reliability and are measured against SLOs SLIs and SLAs is the correct option.

Site Reliability Engineers are explicitly tasked with defining measurable indicators of service health and with keeping systems within agreed targets. They design monitoring and alerting, run incident response and postmortems, perform capacity planning and apply engineering practices to improve reliability over time.

DevOps engineers focus on automating builds releases and developer workflows is incorrect. DevOps engineers do work heavily on automation and developer workflows but DevOps is a set of cultural practices and toolchains rather than a role that is defined by operational reliability metrics.

DevOps roles generally command higher salaries because they are more sought after is incorrect. Compensation varies by region skills and seniority and it is not a reliable way to distinguish the day to day responsibilities of DevOps versus SRE.

A DevOps engineer only handles deploying applications to a public cloud account is incorrect. A DevOps engineer typically works across CI CD infrastructure as code automation and deployments in multiple environments and the statement is an overly narrow description of the role.
