Correct Answer: biased

Solution : The correct answer is the third option.

The term "biased" means showing prejudice or favoritism towards one particular group or point of view. In the context of the sentence, it suggests that there is a perception that the legal code is unfairly prejudiced against women and the poor.

The meanings of the other options are as follows:

Baked: This term refers to the cooking process and does not make sense in the context of describing a legal code.

Frank: While "frank" means open, honest, or straightforward, it doesn't convey the idea of being unfairly prejudiced.

Duplicitous: "Duplicitous" means deceitful or dishonest, which doesn't fit the context of the sentence.

Therefore, the correct word to fill in the given blank is biased.
