According to article i of the constitution, what power does the legislative branch have? creating laws making sure laws are executed interpreting the laws appointing heads of federal agencies

The other options are incorrect because making sure laws are executed and appointing heads of federal agencies are both Executive's powers, and interpreting the laws is a duty of the Judicial Branch.
