Option 1 states that both statements are individually true and that statement II is the correct explanation of statement I. Let`s break it down.

Statement I states that Kali age reflects the presence of deep social crisis characterized by varnasankara, which refers to the intermixing of different social orders. This means that there is a mixture or overlap between different social classes.

Statement II states that the vaisyas and sudras, who are peasants, artisans, and laborers, either refused to perform producing functions, pay taxes, or supply necessary labor for economic production. This resulted in a weakening of the Brahminical social order and social tension.

Option 1 claims that statement II is the correct explanation of statement I. So, according to this option, the intermixing of social orders in the Kali age is due to the refusal of the vaisyas and sudras to perform their economic duties, leading to a weakening of the Brahminical social order.

In summary, option 1 suggests that both statements are true, and the refusal of vaisyas and sudras to fulfill their economic roles is the reason for the social crisis and varnasankara in the Kali age.
