The imagery used in phrases like "If after every tempest come such calms" suggests that the speaker finds satisfaction and happiness in the periods of calm that follow tumultuous and challenging times. Additionally, phrases such as "let the labouring bark climb hills of seas Olympus-high" and "duck again as low as hell's from heaven" convey the idea of navigating through difficult situations, possibly in a metaphorical sense.
The mention of "May the winds blow till they have wakened death" suggests a willingness to face even extreme challenges and dangers, indicating a warrior spirit. The speaker seems to find joy and fulfilment in the adventurous and perilous aspects of life and expresses the sentiment that if it were time to die now, it would be considered a moment of great happiness because the soul feels completely satisfied and content with the present state of fulfilment.
Therefore, the correct answer is D. fulfillment as a warrior, as the speaker's words convey a sense of satisfaction and happiness derived from the challenges and adventures faced in a warrior's life.
