The
correct answer is Option C. A classified advertisement is the
most common type of advertisement in a news paper where the
advertisements are placed under specified headings. They have limited
space and specific information and are charged accordingly. So, if you are 'searching for a paying guest', it would be written
as a
'classified
advertisement'.
Option A is incorrect as a headline gives us a overview of an article.
Option B is incorrect as a poster is used to provide information or promotion in an eye-catchy manner.
Option D is incorrect as a non-classified advertisement or a display
advertisement do not have any specified page or a heading and there is
no limitation of space for the advertiser.
