Solution

The correct options are
B sodium
C phosphorus
Metals like sodium and phosphorus reacts with chlorine gas at room temperature. Gaseous or liquid chlorine usually does not have an effect on elements such as iron, copper, carbon, platinum, oxygen, silver, and steel at temperatures below 230°F. At high temperatures, however, it reacts rapidly with many of the metals, especially if the metal is in a form that has a high surface area (such as when powdered or made into wires).

Hence, answer is A and D.
