Answer:
Option D, none of these options is required for a successful marriage
Step-by-step explanation:
Success of a marriage solely depends on the understanding between the two individuals who get married. Other than this no external factor is responsible for making a marriage successful including religion, premarital counseling , or “living together prior to marriage” etc.

Making marriages successful is a continuous process.
Hence , option D is the correct answer
