A)
By using the General Formula of Alkanes having 4 carbon atoms is

C)
By using the General Formula of Alkanes having 5 carbon atoms is

Tldr, some of the reactants were lost to the surroundings
It's cells become larger in numbers.
Neon is an element and elements are pure oxygen is. Or it is a gas
