Show answer and solution

Correct answer: B. Non-metals

1. Metals are almost all solids at room temperature (mercury being the exception). 2. Non-metals occur as solids (carbon), liquids (bromine) and gases (oxygen). 3. Hence non-metals exist in all three physical states. _Source: RRB Group D CEN-02/2018 PYQ, Q.65._
