Answer:
C,D,,B) The molecule is likely a sugar.
Explanation:
The molecule is(hexose) a glucose.It  is a sugar formed as  the products of photosynthesis.It is also a carbohydrate because all sugars are CHO,although not all CHO are sugars.It is the smallest  components of cell membranes.Protein are the largest components based on molecular mass,while phospholipids are the largest components.
The three major elements in the molecule are Carbon.Hydrogen  and Oxygen. The general formula of carbohydrate is Cx(H2O)y. The ratio of hydrogen to oxygen is 2:1.Thus the hydrate refers to the water content.
Sugar as monosaccharide glucose is the simplest form with general molecular  formula of (CH2O)n  where may be n = 3 to 6. In glucose n=6,and it is called Hexose. Therefore the  molecule of glucose is C6H1206 in ratio 1:2:1.
The arrangement of glucose could be in straight chain or ring structure,Hexose sugar of glucose  and pentose can be ring structure.They have C-H chain length long enough to form ring structure.
In  glucose this can either be alpha or beta ring structure. Therefore the molecule is either the alpha or beta-glucose ring.
