Answer:
B). An alarmed tone.
Step-by-step explanation:
Tone controls the audience's response which makes it significant as it displays the author's point of view or attitude towards a particular subject. Similarly, In this excerpt from Henry Wadsworth Longfellow's "The Warning" the very first-word "Beware" displays the author's tone to warn the readers' that ultimately reflects the alarming tone of the poem which is the chief motive of the poet here. The poem continues to caution people as he says "lion in his path". The allusion to Sampson and his condition("poor, blind") is employed by the poet to enhance the impact of his warning.
