The correct answer is D. Uncertainty of a work.
The idiom “Kab baba marahi, ta kab bara churhi” means “When will the father die, when will the son be married?” It is used to express the uncertainty of a work or event. The idiom is based on the idea that death is inevitable and that no one knows when it will happen. The same is true for other events, such as a wedding. No one knows when they will happen, but they are both certain to happen eventually.
The idiom “Kab baba marahi, ta kab bara churhi” is often used in a humorous way to express the frustration of waiting for something to happen. It can also be used in a more serious way to express the fear of death or the uncertainty of the future.
The other options are incorrect because they do not accurately reflect the meaning of the idiom. Pitri Paksh is a Hindu festival that is celebrated in honor of the dead. Dashgatra is a Hindu religious text that describes the 10 stages of life. Last rites are the religious ceremonies that are performed after someone dies.
