The Methodological Decision Made by an Experimenter Should Be Explained

The methodological decision made by an experimenter should be explained in a manuscript since:

A) Without them the paper is less interesting
B) The choice made influence the design, results, and interpretation of an experiment
C) Since there are relatively few methodological options available to researcher, the rationale for the choices made is necessary
D) The manuscript may appear less important unless the researcher convinces the reader that the decisions were the right ones
