Verify the identity.

(csc^{2} θ + 1) (- cos^{2} θ + 1) = 2 - cos^{2} θ

Which of the following four statements establishes the identity? A.

(csc^{2} θ + 1) (- cos^{2} θ + 1) = - csc^{2} θ cos^{2} θ + csc^{2} θ + cos^{2} θ + 1 = 2 - cos^{2} θ

(csc^{2} θ + 1) (- cos^{2} θ + 1) = - csc^{2} θ cos^{2} θ + csc^{2} θ - cos^{2} θ + 1 = 2 - cos^{2} θ

(csc^{2} θ + 1) (- cos^{2} θ + 1) = csc^{2} θ cos^{2} θ + csc^{2} θ - cos^{2} θ + 1 = 2 - cos^{2} θ

(csc^{2} θ + 1) (- cos^{2} θ + 1) = - csc^{2} θ cos^{2} θ - csc^{2} θ - cos^{2} θ + 1 = 2 - cos^{2} θ
