The correct option when you are checking the price of a specific item in a catalogue is scanning. Scanning involves quickly moving your eyes over the text to find particular information, such as a price, without reading every word. This method is used to locate specific details efficiently, which fits the task of checking a price in a catalogue perfectly. Other options like skimming (getting a general overview), reading closely (detailed reading), or none of the above are not appropriate for this specific task. Therefore, when checking the price of a specific item in a catalogue, you are scanning the catalogue.
