The question asks for the full form of the acronym ILGWU.
ILGWU stands for International Ladies' Garment Workers' Union. This was a major U.S. and Canadian labor union founded in 1900.
It represented workers in the women's garment industry, advocating for better wages, working conditions, and fair treatment for its members.
The union played a significant role in the history of the American labor movement, particularly in the early 20th century.
Therefore, the correct expansion of ILGWU is International Ladies' Garment Workers' Union.
