• B. $1.2$
• C. $1.5$
• D. $3$

Answer 1

The correct option is C

$1.5$

The explanation for the correct option:

(D)

• Carbon dioxide(${\mathrm{CO}}_2$) is made up of one Carbon($\mathrm{C}$) atom and 2 Oxygen($\mathrm{O}$) atom.
• Its density is around $1.98\mathrm{kg}/{\mathrm{m}}^3$ whereas the density of air is $1.225\mathrm{Kg}/{\mathrm{m}}^3$.
• Therefore, Carbon dioxide is about $1.5$ times heavier than air.

Therefore, the correct option is an option(D).
