The correct answer is D) Generally could not vote in states along the eastern seaboard.
Step-by-step explanation:
In the map, those states women could not vote during the early 20th century include states such as New Mexico in the Weast and most states is the eastern seaboard, this includes Vermont, New Hampshire, Massachusetts, Pennsylvania, Kentucky, Virginia, Delaware, South Carolina, North Carolina, Florida, Georgia, among others as all of these states are shown in the map with the same convention (dots) that indicates there were no voting rights for women in these territories. This implies, most of the states with no voting rights were those along the eastern seaboard and therefore it is possible to conclude women "generally could not vote in states along the eastern seaboard".
