What was the 3 part strategy for woman suffrage?

Part 1 they tried to convince states to give them the right to vote. They succeeded in convincing Utah, Wyoming, Idaho, and Colrado. Part 2 they took the states to court pleading that they were being denied their 14th amendment rights. They were denied and voted illegally in 10 states + Washington D.C. Part 3 women wanted a constitutional amendment that would allow them to vote but was shot down. It was accepted in California but got removed.

Ithink it's a, but i might be wrong
