Your question is incomplete, you just posted the sentence you did not indicate what is to be done with them. I am answering the questions on the basis that you want the words that best fit each sentence.
The answers are as follows:
1. The sculptor was pleased with the statue he had WROUGHT from clay.
In this sentence, wrought means to make or fashion something in a specified manner. The word is usually used to describe shaping, molding and manufacturing of objects.
2. Despite many disagreements, the team somehow reached UNANIMITY about what they would do next.
Unanimity means consensus, that is, agreement by all people that are involved in a particular matter. Other words which can be used for unanimity are concord, agreement, harmony, unity, union, etc.
3. Fed up with the king's PLUTOCRACY, the citizens decided to rebel and overthrow him.
Plutocracy refers to government by the wealthy, or a society that is governed by the wealthy. A system of plutocracy allows only the rich to rule, this usually leads to formation of policies which only favor the rich.
4. As the blazing sun continue to PARCH the crops, the woman longed for rain.
Parch, as used in this sentence means to make something become dry through intense heat. It also means to deprive something of water. Other words that can be used instead of parch are: scarring, scorching, blistering, etc.
