Hint: In order to answer the question, first we should know about what is the degree of hydrolysis and then find the quantitative characteristics for the hydrolysis of salts.Also,we should know the difference between all kinds of bases and acids.
Complete answer:
The degree of hydrolysis, $h$ , can be used as a quantitative characteristic for the hydrolysis of salts. It is equivalent to the proportion of the concentration of the hydrolyzed part of the atoms to the all out convergence of the specific salt in arrangement, and as a rule it is little.
The degree of hydrolysis for salt of strong acid and weak base increases with an increase in temperature and with dilution. If acid and base both are weak then degree is independent of dilution.
For salt of strong acid and weak base degree of hydrolysis is:
$h = \sqrt {\dfrac{{{K_w}}}{{{K_b} \times c}}} $
Therefore the value of $h$ increases when ${K_b}$ decreases.
And, here we should also know about the degree of hydrolysis, the degree to which hydrolysis continues is communicated as the level of hydrolysis and is characterized as the division of one mole of the salt that is hydrolysed when the harmony has been accomplished.
Hence, the correct options are (B.), (C.) and (D.).
Note:Degree of hydrolysis always increases with increase in temperature because at elevated temperature increase in ${K_w}$ is greater as compared to ${K_a}$ and ${K_b}$ .To simplify all the parts,we should remember all the graphs related.
