Explanation:

Raw 'Data' is the fundamental input that is manipulated and transformed. Option (d) 'Data' refers to raw facts and figures that, when processed by a computer processor, are converted into meaningful 'information'. Option (a) 'Number' is a specific type of data, but 'Data' is a more comprehensive term. Option (b) 'Processor' is the component that performs the processing, not what is being processed. Option (c) 'Input' is the action of feeding data into the system, not the raw material itself. Therefore, 'Data' is the correct term for what is processed into information.
