Step-by-step explanation:
In a Muslim society such as the Oasis, when a woman is dressed in black, it typically signifies mourning or widowhood (Option A). The black attire is associated with sorrow and loss, adhering to the customs that mark respect for the deceased. In contrast to this somber meaning, in different contexts, black clothing can also be worn for religious significance or as an indication of high social status. However, within the context of the question, black is indicative of mourning or widowhood. The use of color in clothing often carries with it a cultural and societal code, and in the Muslim society of the Oasis, black is a color worn during periods of lamentation for a lost one.
