Your answer should be A.
Evidence :
Globalization led to the widespread of technology. This created more opportunities, and increased communication with different areas of the world.
I'm not sure if this is correct, but I believe it would be that plants need carbon dioxide (plants are living) plants need carbon dioxide to produce oxygen for humans to breathe in, not totally sure if this is correct like I said but I hope I kind of helped. :)
The right answer is polarity.
In chemistry, polarity is a characteristic describing the distribution of negative and positive charges in a dipole. The polarity of a bond or a molecule is due to the difference in electronegativity between the chemical elements that compose it, the differences in charge that it induces, and to their distribution in space. The more the charges are distributed asymmetrically, the more a bond or molecule will be polar, and conversely, if the charges are distributed in a completely symmetrical manner, it will be apolar, that is to say non-polar.
Polarity and its consequences (van der Waals forces, hydrogen bonding) affect a number of physical characteristics (surface tension, melting point, boiling point, solubility) or chemical (reactivity).
Many very common molecules are polar, such as sucrose, a common form of sugar. The sugars, in general, have many oxygen-hydrogen bonds (hydroxyl group -OH) and are generally very polar. Water is another example of a polar molecule, which allows polar molecules to be generally soluble in water. Two polar substances are very soluble between them as well as between two apolar molecules thanks to Van der Waals interactions.

Answer:
mono, di, poly
Explanation:
The smallest molecule would be a monosaccharide because the prefix mono- means one.
The next largest molecule would be a disaccharide because the prefix di- means two.
And the largest molecule would be a polysaccharide because the prefix poly- means many.
