The term you're looking for is "Mortis Causa." This Latin phrase translates to "from the cause of death" and is used in legal contexts to refer to actions taken or properties bequeathed in contemplation of one’s impending death.

To provide a brief overview of the other options:

a. Promulgation refers to the act of formally declaring or announcing something, usually in the context of laws or regulations.

b. Mortis Causa (the correct answer) is specifically associated with matters affecting individuals who are nearing death.

c. Decedent refers to a person who has died, typically used in legal contexts concerning estates or wills.

d. Current Ratio is a financial metric used to evaluate a company's ability to pay short-term obligations, and it is irrelevant in the context of impending death.

Thus, the correct choice is "b. Mortis Causa."
