Correct Answer: praised

Solution : The third option is the correct answer.

Explanation:
Praised means to express approval or admiration for someone's achievements or qualities. In the given context, the sentence suggests that the mother is expressing approval or admiration for the maid's hard work, making praised the correct choice.

The meanings of other options are as follows:

• Priced means to determine the price or value of something.
• Prized means valued highly and regarded as precious.
• Prayed means to communicate with a deity, often through words of devotion or request.

Therefore, the complete sentence would be: My mother praised the maid for her hard work.
