When one tries to solve a problem by using a variety of strategies and eliminating those that do not work, one is using:

A) an algorithm.

B) insight.

C) trial and error.

D) a heuristic.

C) trial and error.

Explanation:

Trial and error is a technique of problem-solving in which repeated attempts are made to get at a solution. In this technique we adopt a method, seeing if it successful to solve the problem and if not we move to a new method. This process will continue until a solution is attained. It is a basic learning method essentially used by all organisms to learn new behaviors.

Trial and error refers to a process where in experimenting is done using various methods to arrive at the most successful answer.

Explain

Option C is the correct answer that best describes how number of strategies are used after eliminating the ones that don't work to arrive at a solution. this method 'Trial and Error' method attempts in accomplishing correct answer after trying various means and strategies. this process gets repeated until and unless correct one is found.
