• It is a colourless and odourless gas.
• Chemically, it is extremely stable in nature.
• It is highly electronegative in nature.

The explanation for incorrect option:

Option A

• Sulphur hexafluoride is non-toxic and non-inflammable in nature.
• Chemically, it is extremely stable in nature.
• It is highly electronegative in nature.
• It is not electro-positive in nature.

Option C

• Sulphur hexafluoride is non-toxic and non-inflammable in nature.
• Chemically, it is extremely stable in nature.
• It is highly electronegative in nature.
• It is not electro-positive in nature.
