Explanation:

Mitakshara was the civil law for upper castes and Dayabhaga was the civil law for lower castes.

This statement is incorrect. Both Mitakshara and Dayabhaga are ancient Indian legal treatises on inheritance. Their applicability was not based on caste but on regional differences. Mitakshara was followed in most parts of India, except Bengal where Dayabhaga was followed.

In the Mitakshara system, the sons can claim right to the property during the lifetime of the father, whereas in the Dayabhaga system, it is only after the death of the father that the sons can claim right to the property.

This statement is correct. In the Mitakshara system, the right to property by birth is recognized. Sons acquire an interest in the ancestral property as soon as they are born. In the Dayabhaga system, sons do not acquire any interest in the ancestral property by birth, and it's only after the death of the father that they can claim a right.

The Mitakshara system deals with the matters related to the property held by male members only of a family, whereas the Dayabhaga system deals with the matters related to the property held by both male and female members of a family.

This statement is incorrect. Both Mitakshara and Dayabhaga systems allow for female inheritance in certain situations. The distinction is not based on gender considerations but rather on when and how heirs can claim rights.

Given the above explanations, the correct statement is the second one.
