Answer: Option (B) is the correct answer.
Explanation:
A compound is defined as a substance in which two or more different elements in a fixed ratio by mass combine chemically with each other.
For example, chemical formula of water is and it is a compound because here two atoms of hydrogen chemically combine with one atom of oxygen.
And, the ratio of these atoms is 2 : 1. A compound can be broken down into simpler substance by chemical means only.
Whereas an element is a substance that contains only same type of atoms that cannot be broken down into simpler substances.
Thus, we can conclude that water is a compound because it always has two hydrogen atoms for each oxygen atom.

Answer:
The chemical formula for the molecule is
Explanation :
Molecular formula : It is the chemical formula which depicts the actual number of atoms of each element present in the compound.
Structural formula : It is a formula in which the lines are used between the bonded atoms and the atoms are also shown in the structural formula.
In the structural formula, the lines are used between the atoms.
As per given information of compound we conclude that, there are 4 carbon atoms, 9 hydrogen atoms and 2 oxygen atoms.
Thus, the chemical formula for the given molecule will be,
