The Second Continental Congress was held in 1775 and produced several documents, but it is most famously associated with the Declaration of Independence, which was adopted later in 1776. However, in 1775, they also worked on the Declaration of Rights and Grievances, which addressed colonial concerns to King George III. Therefore, if you are specifically looking for a document produced in 1775, the correct answer would be:
The Declaration of Rights and Grievances.
If you mistakenly meant to refer to what is most commonly associated with the Second Continental Congress overall, you could reference the Declaration of Independence, but that was in 1776, not 1775.
