- All of the above/given.

Explanation:

As the question states, a director or screenwriter is required to make alterations to the original version of the story in order to present more freshly and effectively (to present on the radio, film or television). All the provided options apply to this claim as there is not one specified reason for which the original version needs to be modified. 'Adding action and excitement' would add to present the same story with a fresh touch which the audience would like while 'simplifying the story and deny confusion' and 'removal of scenes that seem unnecessary to the overall theme' would aid to rectify the mistakes that occurred in the original version and offer it in a more sharp, succinct, and effective manner(without any flaws).  

The 'cutting or shortening of the story' and 'updating it for a modern-day audience' would turn it more audience-friendly depending on the domain(radio, film, or TV) for which it is being adapted and its audience group. Thus, all of the given points display the reasons for which the original version of the text or story must be molded.
