On which day are Orthodox Jewish funeral rites not held?

Orthodox Jewish funeral rites are traditionally not held on Saturday, as this day is designated for the Sabbath, a day of rest and spiritual reflection. During the Sabbath, which begins at sundown on Friday and ends at nightfall on Saturday, work and many activities, including funerals, are prohibited to honor the sanctity of the day. This means that any necessary funeral arrangements and mourning practices must be postponed until after the Sabbath concludes.

In contrast, the other days mentioned in the options do not have such prohibitions, allowing for funeral rites and related activities to take place without conflicting with religious observances. Friday is often a day when funeral preparations may occur before the Sabbath begins, while Sunday and Wednesday do not interfere with the religious observance, making them acceptable days for conducting funeral rites.
