The correct answer is D. no article.
The word “union” is a common noun, which means that it refers to a general class of things. In this case, the union is a group of workers who have joined together to bargain with their employer for better wages and working conditions.
Common nouns are not typically preceded by articles, unless they are used in a specific or unique sense. For example, we might say “the union” to refer to a particular union, such as the United Auto Workers.
In this case, the union leader is not being identified as a specific individual, so the article “a” or “an” is not necessary.
