Answer: The correct answer is Option d.

Explanation:

Dry air is composed of a mixture of gases like argon, oxygen, nitrogen, carbon dioxide and many other gases present in trace amount.

The percentage of these gases by volume in dry air is:

Carbon dioxide = 0.03%

Argon = 0.93%

Oxygen = 20.95%

Nitrogen = 78.09%

Hydrogen = Trace amounts

From the above percentage values, we can easily say that nitrogen has the highest percentage by volume in dry air. Hence, the correct option is d.
