<u>Answer: </u>The correct answer is Option B.
<u>Explanation:</u>
The given elements that is sodium and sulfur are the elements which belong to the same period that is third period.
As, the electrons are added up to the same shell across a period, the number of protons also increase and hence, they attract the electrons more effectively. This means that the effective nuclear charge also increases and the size of the sulfur thus shrink and hence, the size (atomic radius) of sodium is the largest amongst third period.
Therefore, the correct answer is Option B.
If one of the waste products of cellular respiration is CO2 by means of exhaling, then the rate of cellular respiration increased.
<h3>What is Cellular respiration?</h3>
This consists of series of reactions which combine the chemical energy from foodstuffs and oxygen to form ATP and other waste products such as carbon dioxide and water.
During this process, the carbon dioxide is transported from the mitochondria out of the cell, to the red blood cells, and to the lungs where they are exhaled.
This therefore depicts that the cellular respiration increased as a result of the carbon dioxide given off via exhalation and thereby makes it the correct choice.

3. Hypothesis-- creating an educated guess as to the answer of your question.
It is B, and also for a moment I didn't understand that 4.69 x 10^22. I almost did this whole problem wrong.
