Final answer:
The number of processes scheduled on an AWS server is 'n', as directly stated in the question.
Step-by-step explanation:
The question posed pertains to the number of processes scheduled on an AWS server. Without additional context or information, the answer that fits the question most directly is (c) n. The letter 'n' is commonly used in computer science and various fields of mathematics to represent a variable quantity. Since the question states that 'n processes are scheduled,' it implies that there are n processes. If 'n' is an integer value, then the number of processes scheduled is exactly that number.
