Which of the following reasons best explains why a scientist would want to replicate gregor mendel's pea plant experiment? a. to discover new aspects of the natural world b. to test the predictions of current theories c. to explain recently observed phenomena d. to test the conclusions of prior investigations

The correct answer will be option-D.

Explanation:

A scientific experiment is performed to test the predicted hypothesis as experiment provides the results or evidence. The analysis of the result will result in the formation of a theory or law.

An experiment is designed in such a way that it can be performed or replicated by another scientist working on the same issue with the aim to test the validity of the conclusions.  Therefore in a given question, the main aim of another scientist may be to test if the conclusions still hold true or not.

Thus, option-D is the correct answer.
