Advntage:
 provides CPU scheduling, memory management, file management, and other operating system functions through system calls. The other one is that it is a single large process running entirely in a single address space.
Disadvantage: if anyone service fails it leads to an entire system failure

Answer:
The answer to this question is given below in the explanation section
Explanation:
The correct answer is RAM.
RAM is used for storing programs and data currently being processed by the CPU.  So, the data in the RAM, can be easily accessible and processed by the CPU more fastly. 
While Mass memory and neo volatile memory is not correct options. because these types of memory can stores a large amount of data but CPU fetch data from these memories into RAM. and, RAM can only be used by the CPU when performing operations.
