Answer: b. fire, heat, and brightness
Step-by-step explanation:
In the Tiger, William Blake's poem, the speaker sees the tiger and asks certain questions about the animal's appearance and its creator. The tiger is described as 'burning bright':
"Tyger, Tyger, burning bright
In the forests of the night.."
The symbol of fire is mentioned multiple times throughout the poem :
"In what distant deeps or skies Burnt the fire of thine eyes?"
"On what wings dare he aspire? What the hand dare seize the fire?"
The correct answer is, therefore, that the tiger is compared to fire, heat and brightness.
