Explanation:

While computers possess significant processing power and storage capabilities, their capacity is ultimately 'Limited' by physical hardware constraints, available memory, and processor speed. Option (a) 'Limited' is the most accurate description. It is not (b) 'Unlimited' as there are always physical and technological boundaries. Describing it as (c) 'Low' or (d) 'High' is subjective and depends on the specific computer and context, but fundamentally, it is finite and thus limited.
