Leroy and samantha are a married, dual-career couple. when leroy comes home from work, he participates fully in both child care and household tasks. they are a/an dual-career family

The answer is role-sharing
role-sharing family is a form of marriage style that does not follow traditional role of coupling where one partner had the role to collect money while the other ahd the role to maintain the household.
In a role-sharing family, both parents contribute to all aspects that make the family up running (both of them had jobs and both of them are doing chores)

Yes all of them are right
