The correct answer is: C. determined , undertake
The word “determined” means “having a firm purpose or resolve.” The word “undertake” means “to take on or accept responsibility for a task or project.” In this context, the sentence is saying that the person is willing to take on any kind of work with due sincerity. This means that they are committed to doing their best work, regardless of the task at hand.
The other options are incorrect because they do not accurately reflect the meaning of the sentence. The word “fond” means “having a strong liking or affection for someone or something.” The word “reluctant” means “unwilling or hesitant to do something.” The word “eager” means “having or showing a strong desire or enthusiasm.” The word “avoid” means “to keep away from or stay clear of.” The word “ignore” means “to refuse to take notice of or pay attention to.”
In conclusion, the correct answer is: C. determined , undertake
