Final answer:
The correct pair of adjectives to fill in the blanks is 'bleues, oranges' in French.
Step-by-step explanation:
The correct pair of adjectives to fill in the blanks would be bleues, orange.
In French, adjectives agree in gender and number with the noun they modify. Since the noun 'valises' (meaning 'suitcases') is feminine and plural, the adjectives also need to be feminine and plural. 'Bleues' is the feminine plural form of the adjective 'bleu' (meaning 'blue'). 'Orange' remains the same because it doesn't change for gender or number.
Therefore, the correct answer is:
OD. 'bleues, oranges'.
