Which of the following is NOT one of the qualifications mentioned for admission?

The correct answer is based on the principles and prerequisites outlined in Masonic tradition. Being duly prepared and worthy, having suitable proficiency in the preceding degree, and being properly vouched for are all important qualifications for admission into a Masonic lodge, as they ensure that candidates uphold the values and commitments of Freemasonry.

In contrast, possessing advanced knowledge of masonry is not typically required for admission. While existing knowledge can be beneficial, the emphasis is primarily on the candidate's preparedness, moral character, and basic proficiency rather than an advanced understanding of Masonic principles. This distinction helps to emphasize that Masonic membership is accessible to those who embody certain qualities and not solely to those with extensive prior knowledge. Therefore, option C stands out as the qualification that is not explicitly required for admission.
