A hyperbole is an extreme exaggeration. The complete opposite of an understatement.
A. "They'll flock in droves" is one example of a hyperbole.
C. "They'll fight for that stock" is an example because they are unlikely to actually physically fight one another for some stock. There would be competition but no fighting.
Finally, because D. and E. use the terms "forever" and "never", respectively; they can be considered a hyperbole as it is difficult to ascertain if something can truly be forever and never forgotten.
Hyperbole is a literal exaggeration. It contains strong feelings and impressions. Therefore, hyperbole is also known as intensifier. In the question correct options are A, C, D. In option A in droves is a phrase which means in large numbers and it is definitely exaggeration, an imaginative expression of something; option C exaggerates the actions of people who would do anything to get the stock; option D is interpreted as "a successful man forever" which is another example of exaggeration.
