Answer:
Option A, similarity of values
Step-by-step explanation:
People with same values preferably fall to like each other and hence they talk more as compared to people sharing other common bases such as family status, academic profile and attractiveness.
It is very difficult to sustain a relationship if there is a difference in values.
People sharing common thoughts on relationship’s importance tend to have a better understanding and coherent mutual relationship.
Differences in values between two people in relationship tend to portray two different values for the same relationship which is difficult to carry on in long run.
Thus, if values are same, a relationship could be long lasting and fruitful
Hence, option A is correct
