Which of the following is a non metal that remains liquid at room temperature?

A. Phosphorous

B. Bromine

C. Chlorine

D. Helium

Answer: Option B

Solution(By Examveda Team)

Bromine is a chemical element with symbol Br and atomic number 35. It is the third-lightest halogen, and is a fuming red-brown liquid at room temperature that evaporates readily to form a similarly coloured gas. Its properties are thus intermediate between those of chlorine and iodine.
