Answer:
The rights of women.
Step-by-step explanation:
The group of 55 delegates from the states convened in Philadelphia in 1787 to discuss the various issues concerning the nation. It was in this convention that issues like slavery, the federal and state governing rules, issues of representation, etc. are discussed to comply or be feasible for everyone, be it the Northern states or the Southern ones.
The Philadelphia Convention, which would later become known as the Constitutional Convention, was called to discuss and find probable solutions for the country's problems. These problems range from what terms and issues would be included in the constitution, issue of representation, slaves, or what will be covered in the federal government and the state government. But one issue that was not a part of the convention's discussion was that of women's rights. Women, or even any issues regarding the female gender, were brought up or considered.
Thus, the correct answer is the second option.
