The correct answer is option a.  "There was a steady increase in the number of all women voting".

Explanation:

In the United States, women were granted the right to vote once the 19th Amendment was ratified on on 26 August 1920. From that year to the following 20 years in 1940, there was a steady increase in the number of all women voting. This happened in part by different events that allowed that women who were immigrants could vote as well. For instance,  the Magnuson Act in 1943 at which chinese immigrats were granted the right to vote; or the McCarran-Walter Act in 1952 that allowed that  first generation Japanese Americans could vote.

the answer is c. they believed the royal family should hold all the power.
