Answer:
Shrink the primary partition and create a simple volume for Windows 10.
Explanation:
The EFI’s partition space, after it is shrunk, will not be enough to install your Windows 10 since by default; it can only hold a maximum space of about 250MB to 500MB. Some windows versions call this partition EFI while others refer to it as system reserved. Windows uses EFI partition to hold on to essential components that make your PC boot like boot loaders, system utilities, and a few more.
The answer is B.
When you shrink your volume, whether it is local disk C or a primary partition with plenty of free space, it will create unallocated space. Right click on the unallocated space and create a New Simple Volume that will let you format your partition, assign a drive letter, and install your Windows 10 Operating System.
