Carbon compound chemistry

i am confused by the wording what does the question ask and how is it solved?

Carbon is burnt in excess oxygen so considering all the carbon in the compound is present in the carbon in CO2.
n(CO2)=4.77/44(Mr CO2)=0.1

Also the molar ratio of C:CO2=1:1
Moles of C=0.1
Mass C=0.112=1.2g
which is closest to 65 the answer is thus E.

There’s also a typo in the question! Remember the Mr of Oxygen is 16 not 6
