In Microsoft Azure, What server size/series uses credits and slows down if the credits run out?

In Microsoft Azure, What server size/series uses credits and slows down if the credits run out?

• F series
• D series
• B series
• A series 

EXPLANATION

The B-series VMs are ideal for workloads that do not need the full performance of the CPU continuously, like web servers, proof of concepts, small databases and development build environments. These workloads typically have burstable performance requirements. The B-series provides you with the ability to purchase a VM size with baseline performance and the VM instance builds up credits when it is using less than its baseline.
When the VM has accumulated credit, the VM can burst above the baseline using up to 100% of the vCPU when your application requires higher CPU performance. If the CPU usage goes above 25% it will start to consume credit. WHen the credits run out the server will run at baseline rate.
