Correct answer choice is :
D) The adoption of aggressive tactics by suffragists
Step-by-step explanation:
In 1918, following years of intense effort, women eventually won the freedom to vote. To mark this anniversary, we asked 100 legislators and campaigners, including Nicola Sturgeon, Diane Abbott, and Theresa May, to show politically and individually on this important ceremony. One success commenced to another. The obstacle to women going for the government was immediately discarded, and the first female MP was selected that year.
