Hi Scarlet,
Let’s go over each option.
A. Not say a word. (Not saying a word to the boss might make Lennie seem rude).
B. Give him his work ticket. (This might make Lennie seem thoughtful, but a little too cocky).
C. Introduce himself. (This might make Lennie seem polite).
D. Show the boss his strength. (This might make Lennie seem impressive, but could also make him appear overbearing).
Now ask yourself, what would YOU do when meeting a potential boss? Or in general, what would you do when meeting a person in general?
One of these answers does not have a negative implication.
