Which one of the following is the correct sequence of the given substances in the decreasing order of their densities?

Steel>Mercury>Gold

Gold>Mercury>Steel

Steel>Gold>Mercury

Gold>Steel>Mercury

Correct Answer: Option B

Explanation

1. The question asks for the correct sequence of substances in decreasing order of their densities. 2. Typical densities at room temperature are approximately: Gold: 19.3 g/cm³; Mercury: 13.5 g/cm³; Steel (varies): ~7.85 g/cm³. 3. Arranging these in decreasing order of density gives: Gold > Mercury > Steel. 4. Sequence (B) matches this order.
