Explanation:

2 cos2 θ - 5 cos θ + 2 = 0

2 cos2 θ - 4 cos θ - cos θ + 2 = 0

2 cos θ (cos θ - 2) - 1 (cos θ - 2) = 0

(cos θ - 2) (2 cos θ - 1) = 0

cos θ = 2 or cos θ = 12

cos θ = 2 is not possible.

So, cos θ = 12

sec θ = 2

tan θ = sec2θ-1 = 4-1 = 3

∴ (sec θ + tan θ) = 2 + 3

Hence, the correct answer is Option A
