Polarisation is the distortion of the shape of anion by an adjacently placed cation. Which of the following statement is correct?

AMaximum polarisation is brought about by cation of high charge
Correct Answer
BMaximum polarisation is brought about by cation of low charge
CA large cation is likely to bring about a large degree of polarisation
DA small anion is likely undergo a large degree of polarisation

Solution

Smaller the size and higher the charge on cation will have higher polarizing power and thus can polarize the electron charge density of the nearby anion to a greater extent.
For anions will larger size and high charge, polarizability will be high.
Hence, option $$A$$ is correct.
