<em>The correct option is A) It was used to influence public opinion</em>
Explanation:
In 1898, a conflict arose between Spain and the United States which was termed as Spanish- American war.
In the late 1890's journalists, Joseph Pulitzer and William Randolph Hearst used yellow journalism to influence and agitate the public of United States against Spain. Yellow journalism provided no legitimate well- searched news. It just made agitating headlines so that the news could be eye-catching and spread among people of the United States.
