Answer : Carbon tetrachloride, 
 will show the greatest freezing point lowering.
Explanation :
For non-electrolyte solution, the formula used for lowering in freezing point is,

where,
 = lowering in freezing point
 = molal depression constant
m = molality
As per question, the molality is same for all the non-electrolyte solution. So, the lowering in freezing point is depend on the 
 only.
That means the higher the value of 
, the higher will be the freezing point lowering.
From the given non-electrolyte solutions, the value of 
 of carbon tetrachloride is higher than the other solutions.
Therefore, Carbon tetrachloride, 
 will show the greatest freezing point lowering.

Answer:
• potential for a species to increase in number 
• the heritable genetic variation/ which results from mutation in dna
• the size of a population increases 
• competiton for resources that are limited in that specific environment. 
Explanation:
these are all factors that would affect natural selection although there are many more.
