The correct option is D.
When one is about to start using a particular social media, it is needful that one first creates a trial for some important reasons. Firstly, creating a trial gives one the opportunity to become familiar with the program, so that one will know what using the media entails. Creating a trial also gives one the opportunity to decide whether the social media is fit for one's needs or not. During this period, one will surely make some mistakes, but their impacts will be minimized because one is just trying out the social media.
