Instructions
In each of the question, the underlined word is used in four different ways. Choose the option in which the usage of the word is incorrect or inappropriate.
Solution
Option A:Â "She could not master the courage to tell her friend"Â about her loss. It refers to the fact that she could not gather enough courage, so muster is the correct word to be used here, not master.
Mastered means to have gained expertise in something, so all other uses are correct.Â
