Answer:
A). Is requested by your lawyers if they feel that it is impossible for you as a defendant to get a fair trial due to media coverage.
Explanation:
As per the question, a request for 'change of venue' in a criminal proceeding could be 'requested by the defendant when they feel a threat that it is difficult or rather impossible to have a fair trial due to media coverage.' Such a request is only allowed for the accused and only when he/she is able to display a reasonable probability that their right is being disregarded. Thus, the accused can demand the 'change of a venue' if he/she feels that pretrial publicity may prevent a fair trial. Therefore, option A is the correct answer.
