Answer: C. both single threaded and multithreaded
Step-by-step explanation:
A process can either be single threaded and multithreated. Single threaded processes is when the execution of instructions are in a single sequence i.e the sequence is one command at a time while for multithreaded processes, there are. execution of several multiple parts of a program that occurs at the same time.
A single threaded process only runs on one CPU, whereas for the execution of a multi-threaded, it may be divided amongst the available processors.
