Victoria Day is celebrated on the:

Discover Canada records this in one direct label. The guide writes: Victoria Day Monday preceding May 25 (Sovereign's birthday). The date the test wants is therefore the Monday preceding May 25.

The day honours the Sovereign's birthday. Discover Canada commits Victoria Day to the Sovereign's birthday. So Victoria Day is the official Canadian celebration of the reigning monarch's birthday — anchored to May 25, which was Queen Victoria's birthday in the 19th century. The Monday-preceding-May-25 placement creates a long weekend.

Queen Victoria is foundational to Canadian identity. Discover Canada writes that "Canada has been a constitutional monarchy in its own right since Confederation in 1867 during Queen Victoria's reign" and that "Ottawa, located on the Ottawa River, was chosen as the capital in 1857 by Queen Victoria, the great-great-grandmother of Queen Elizabeth II." So Queen Victoria is connected to Canada's founding moments — both choosing the capital in 1857 and reigning at the time of Confederation in 1867. Victoria Day honours her birthday and, by extension, the reigning Sovereign's birthday in modern Canada.

Victoria Day is one of three Monday holidays. Discover Canada places Victoria Day among the Canadian holidays observed on Mondays: Victoria Day (Monday preceding May 25), Labour Day (first Monday of September), and Thanksgiving Day (second Monday of October). All three create long weekends. Victoria Day specifically marks the late-spring transition — traditionally signalling the start of the summer season in Canada. The full Canadian holiday calendar includes (in order): New Year's Day; Sir John A. Macdonald Day; Good Friday; Easter Monday; Vimy Day (April 9); Victoria Day; Fête nationale (Quebec) on June 24; Canada Day on July 1; Labour Day; Thanksgiving Day; Remembrance Day (November 11); Sir Wilfrid Laurier Day (November 20); Christmas Day; and Boxing Day. So Victoria Day fits between the Easter cluster and Fête nationale Quebec — the spring-into-summer transition holiday. So when the test asks the date pattern of Victoria Day, the source-precise answer is the Monday preceding May 25.

The question is testing whether new citizens know when Victoria Day is observed. Discover Canada commits to one timing: the Monday preceding May 25. The right test answer matches that.

The wrong answer choices each substitute a different timing. "First Monday of May" misframes the source — Victoria Day is anchored to the May 25 date, not the first-of-month Monday. "Last Monday of May" misframes too — the day is the Monday immediately PRECEDING May 25, which can fall on a date earlier than the last Monday. "May 24" is too specific — Victoria Day is a moveable Monday, not a fixed-date May 24. Only the Monday-preceding-May-25 answer matches.
