Which problem-solving strategy or method is correctly matched with its definition?

Basing this off of the problem choices of the following: A) means-end analysis - dividing a problem into smaller, more manageable tasks B) using subgoals - discovering a problem's solution in a sudden moment of clarity C) trial and error - solving a problem by making a series of attempts and eliminating unsuccessful ones D) insight - progressively reducing the discrepancy between a problem's current state and the goal state The answer would be (C) trial and error. The reason this is the correct answer is that it is a correct statement of fact. When working on solving a problem if someone is using trial and error, they will test out different theories before coming to the correct answer.

In line with other previous and contemporaneous proposals, in 1912 the meteorologist  alfred wegener  amply described what he called continental drift, expanded in his 1915 book the origin of continents and oceans and the scientific debate started that would end up fifty years later in the theory of plate tectonics.
