set aside

The most appropriate word to fill in the blank and make a meaningful sentence is:set aside

The corrected sentence would be: "Mother set aside some food for the old beggar woman."

Explanation:
"Set aside" means to reserve or keep something for a particular purpose or person. In the context of the sentence, it suggests that the mother reserved or allocated some food specifically for the old beggar woman, which makes the sentence meaningful.

Set up implies preparing something in a more elaborate way, which might not be the case for simply saving some food.

Set out suggests starting a journey, which isn't the action here.

Set aside specifically means to reserve or keep something separate for later use. This perfectly captures the act of saving some food specifically for the beggar woman.

Set in refers to the beginning of something like weather or a trend, and doesn't fit the context.
