Your answer would be choice B,it offers a counterclaim to the first stanza, which is then rejected in the third stanza. I only know this because I just had this questionif we are talking about the same question.
Answer:
if leg a is the missing side, then transform the equation to the form when a is on one side, and take a square root: a = √(c² - b²)
if leg b is unknown, then. b = √(c² - a²)
for hypotenuse c missing, the formula is. c = √(a² + b²)
The answer is A. a simile, personification, and metaphor.
