a.

Register usage is managed by the processor, but stack usage is not.

b.

Register usage is for long-term storage, but stack usage is for short-term storage.

c.

Register usage is for data that fits into the processor's registers, but stack usage is for larger variables or data that needs to be stored in RAM.

d.

Register usage is for data structures, but stack usage is for individual values.

Answer: (c).Register usage is for data that fits into the processor's registers, but stack usage is for larger variables or data that needs to be stored in RAM. Explanation:Registers are used for storing the most immediate data, while the stack is used for storing slightly longer-term data, such as local variables that don't fit into the processor's registers or variables that must be stored in RAM.
