Correct answer: basic_scaling with max_instances set to 5 and idle_timeout set to 10m.
Why this is the answer
The correct option is basicscaling with maxinstances set to 5 and idletimeout set to 10m because App Engine Standard's basicscaling type allows you to specify a maximum number of instances (maxinstances) to cap resource usage and costs. The idletimeout parameter defines how long an instance can be idle before it is shut down. manualscaling requires you to manage instances yourself and doesn't automatically scale down. While instances can be set, it's typically for fixed numbers, not a maximum limit for dynamic scaling. minpendinglatency is used with automatic scaling to control when new instances are started based on request queue times, not for setting a hard instance limit.
