The correct answer is A. livelihood.
Livelihood is the means of supporting oneself and one’s family, especially by one’s own work. It is a noun derived from the Old English word “liflade,” which means “way of life.”
The word “livelihood” is often used in the context of poverty and economic hardship. For example, someone who is struggling to make ends meet might say that they are “struggling to make a livelihood.”
The word “livelihood” can also be used in a more general sense to refer to any means of support. For example, a farmer might say that their livelihood is dependent on the weather.
The other options are incorrect because they are not real words.
