Answer:
Step-by-step explanation:
a. x rho y ---> x is the husband of y.
Not reflexive, because x cannot be husband of x, not symmetric also not transitive
b. x rho y ---> x is the spouse of y.
Not reflexive, but symmetric because when x is the spouse of y, y is the spouse of x. Canot be transitive
c. x rho y ---> x has the same parents as y.
This is reflexive, symmetric and also transitive. Because when x and y have same parents and y,z have same parents then x and z have same parents.
d. x rho y ---> x is the brother of y
Not reflexive, need not be symmetric if x is a girl.
Transitive is true.
