From the given pair of words, choose the one which do not carry the same relationship:

Parent : Offspring

(1) Cow : Calf

(2) Hen : Chicken

(3) Mother : Daughter

(4) Brother : Cousin

4

The answer is Option 4: Brother : Cousin. The first three pairs of words exhibit a parent-child relationship. A cow is the parent of a calf, a hen is the parent of a chicken, and a mother is the parent of a daughter. In contrast, a brother and a cousin are not necessarily related as parent and child. While they may have a family connection, their relationship is not based on the parent-offspring connection. Therefore, option 4 is the answer.
