The correct answer is C. Previewing
Explanation:
Previewing is a reading strategy used before reading a text to get a general idea about the topic and focus of the text. Previewing means you look at the titles, headings, captions, graphs, images or elements that stand out so you can an idea before reading. This reading strategy differs from skimming because in skimming you take a look at all the text including the main paragraphs or bolded sections in them, and in previewing you do not read paragraphs but only titles and other elements such as images. According to this, previewing is the strategy you are using when you only read the title, section headings, and captions.
