Which of the following is the most common way to determine whether a counseling program took place and the form it took during implementation?

A) Post-research analysis
B) Observational methodology
C) Qualitative data analysis
D) Quantitative research

Observational methodology is the most common way to determine whether a counseling program took place and the form it took during implementation. This involves observing the program in action and recording the activities that occur. Post-research analysis, qualitative data analysis, and quantitative research may be used as follow-up measures to evaluate the program's effectiveness, but they do not provide information about whether the program was actually implemented or how it was carried out.
