Explanation:

Given information:
- Average age of husband and wife at the time of marriage = 23 years
- After 5 years, they have a one-year-old child

Calculating the current average age:
- The sum of ages of husband and wife at the time of marriage = 23 + 23 = 46 years
- Total age after 5 years = 46 + 5 + 5 = 56 years
- Total age after the addition of the child's age (1 year) = 56 + 1 = 57 years

Calculating the current average age of the family:
- Average age of the family = Total age / Number of family members
- Number of family members = 2 (husband and wife) + 1 (child) = 3
- Average age of the family = 57 / 3 = 19 years

Therefore, the average age of the family now is 19 years (option B).
