Common Surname:
The correct answer to this question is option 'A', which is "Surname". A surname is the family name or last name that is shared by all the members of a particular family. It is a common practice in many cultures for family members to have the same surname, which helps in identifying and distinguishing one family from another. Let's understand why the other options are not correct.

Height:
The option 'B' suggests that every member of the family has a common height. However, this is not true as height can vary among family members due to various factors such as genetics, nutrition, and lifestyle. While family members may share certain physical characteristics due to genetics, height is not necessarily one of them.

Work:
The option 'C' suggests that every member of the family has a common profession or work. However, this is unlikely to be true for every family as individuals have different interests, skills, and career choices. While it is possible for some families to have a common profession that is passed down through generations, it is not a universal characteristic of all families.

None of these:
The option 'D' suggests that none of the given options is correct. However, this is not the case as the correct answer is indeed option 'A', which states that every member of the family has a common surname.

In conclusion, the common characteristic that every member of the family has is a common surname or last name. This is a widely recognized practice in many cultures, where family members share the same surname, indicating their familial relationship and identity.
