Quick Solution

This puzzle requires us to first determine the two married couples in the family and then deduce the colour preferences for each person to find a matching combination.

1. Identifying the Married Couples

A step-by-step analysis of the family relations clues ("A is the grandmother of F", "C is the daughter-in-law of E", "B is the son of D") reveals the family structure and its two married couples:

• Couple 1 (The Grandparents): The clues show that A (Grandmother) is married to E (Grandfather).
• Couple 2 (The Parents): Their son, D, is married to his wife (and E's daughter-in-law), C.

2. Deducing the Colour Combination

The key clue for solving the colours is: "Wife of the husband having a choice for Green colour likes Yellow."

• The only husbands in the family are E and D.
• We know from another clue that C (who is D's wife) likes Black. Therefore, D cannot be the husband who likes Green, because if he did, C would have to like Yellow.
• This means the other husband, E, must be the one who likes Green.
• The clue then tells us that E's wife, who is A, must be the one who likes Yellow.

This successfully identifies the colour combination for one of the married couples: A and E.

3. Conclusion

- The colour combination for the grandparent couple (A and E) is Yellow and Green.
- Checking the options, this matches the combination given in option D.

Final Answer: A possible colour combination of one of the couples is Yellow-Green.
