. . . . . . . . women live longer than . . . . . . . . men.

The correct answer is: D. no article, no article

The reason is that the word "women" is a general noun, and it does not need an article. The word "men" is also a general noun, and it does not need an article.

The word "a" is used before a singular noun that is not specific. For example, "I saw a dog." The word "the" is used before a singular noun that is specific. For example, "I saw the dog that ate my homework."

In the sentence "Women live longer than men," the words "women" and "men" are general nouns. They are not specific, so they do not need articles.

Here are some other examples of sentences that do not use articles with general nouns:

• Children need love and attention.
• People need to eat to survive.
• Animals need food, water, and shelter.

I hope this helps!
