“A cell selectively affected by a particular agent, such as a virus, drug, or hormone.”
Answer:
The correct answer is option 2.
Explanation:
Colligative property is defined as property which depends upon only on the numbers of particles of solute dissolved in definite amount of solvent, It do not depend on the nature of the solute.
For example : NaCl solution with 0.4 molal will show same colligative properties as a that of the glucose solution with 0.04 molal concentration.
The following are the examples of colligative property:
1. Relative lowering of vapor pressure.
2. Osmotic pressure
3. Elevation in boiling points
4. Depression in freezing point
The key enzyme in the regulation of the citric acid cycle is citrate synthase. It functions in the mitochondria.
<h3>Citrate synthase and cellular respiration </h3>
Cellular respiration is a series of reactions that produce ATP by using the energy stores in the chemical bonds of foods.
Cellular respiration is divided into glycolysis, the citric-acid cycle and oxidative phosphorylation.
Citrate synthase is an enzyme found in the mitochondrial matrix, which is involved in the citric acid cycle.

Explanation:
Sucrose will be the most effective. Hence, option D is correct.
<h3>What is sucrose?</h3>
Sucrose is simply the chemical name for sugar, the simple carbohydrate we know and love that is produced naturally in all plants, including fruits, vegetables and even nuts.
When salt or sugar (a solute) is combined with water or ice (a solvent) and is evenly distributed, the freezing point is lowered.
→ 
Hence, sucrose will be the most effective.
