Dalton's Law of Partial Pressures States Which of the Following

Dalton's Law of Partial Pressures states which of the following?

A) The total pressure exerted by a mixture of gases in a container is equal to the highest partial pressure exerted by any of the gases in the container.
B) The total pressure exerted by a mixture of gases in a container is the sum of the pressures that each gas would exert if present alone under similar conditions.
C) The total pressure exerted by a mixture of gases in a container is the average of the pressures that each gas would exert if present alone under similar conditions.
D) The total pressure exerted by a mixture of gases in a container is inversely proportional to the pressure that each gas would exert if present alone under similar conditions.
E) The total pressure exerted by a mixture of gases in a container is equal to the range of partial pressures of each gas in the container.
