The correct answer is A. A newspaper
Step-by-step explanation:
A print research source is a type of source that is created using paper and ink and contains texts or images that provide information about the topic that is being researched. This source differs from other such as websites because websites are digital, from podcasts because these contain only auditive information and from CD or DVD because even if they can contain images, sounds and text they are also displayed on a screen which means they are not printed. Therefore, the one that is an example of a print research source is a newspaper because this is the only printed source as traditional newspapers are created using paper and ink and also this contains information that might be valuable in research.
