Elasticity and agility is the correct answer because it pertains to the capacity to scale computing resources up or down efficiently, allowing businesses to adjust to workload changes without over-provisioning or incurring unnecessary costs. This directly results in operational flexibility and cost efficiency, supporting quick adjustments in an organization’s scale of operations, which is vital for rapid innovation. 'Unlimited storage capacity' might seem relevant, but it lacks the focus on cost efficiency and business agility provided by elastic scaling. 'Global presence of data centers' deals with the widespread availability and redundancy of resources geographically, which is beneficial for latency and global reach rather than scalability or innovation. 'Exclusive access to new features' is misleading since cloud service features are not exclusive to any specific users. Lastly, 'Inclusion of all third-party software licenses' is beyond the scope of the question, which focuses on elasticity and scaling rather than software licensing strategies.
