Lise Marie J. de Baissac came from a French family. She was born in Mauritius and had British nationality. She was the superstar of the Special Operations Team at the time of WW-II. She was a dignified agent who, multiple times, risked her life in order to work in national spy operations. After the war seized, she was received numbers of gallantry prizes.
However, the reason after every option for its acceptance or nonacceptance as the answer is mentioned beneath each point. Anyhow, the correct answer is darkened.
A. "When she ... lived there."
This line only defines a specific detail about how the special agent survived through a fake name as a spy. No theme is described through this sentence.
B. "Baissac’s goal ... resistance groups."
This statement the agent’s motive and the way she enacted the task provided. Still, the complete idea is not expressed within the line.
C. "Baissac did ... her tasks."
The writer is praising the efforts of Baissac in this sentence. He again writes how much hard work the agent did in order to achieve the national goals.
D. "As a ... German troops."
This is the statement that definitely defines the central idea of the excerpt. When we break this line into sections, we can see that it illustrates that she performed multiple essential tasks when appointed in Normandy. The phrase “sometimes dangerous tasks” describes the critical nature of the job she handled in there. And, also the opposition (German troops) is clearly mentioned in this sentence which helps to convey the idea very clearly.
