A.

Explanation:

This is the total weight of CO2. Now, to know the percent composition of Carbon and Oxygen . We will divide their weight with the total weight of CO2. % C = 12.01/44.01 = 0.2729= 27.29% (we will divide 0.2729 with 100 to take the percentage) we round off 27.9 into 27.3(or the answer 27.30 is also the same)
