A Correct answer
Explanation

In trigonometry, cot is the abbreviation for cotangent, which is defined as the ratio of the adjacent side to the opposite side in a right triangle (cos/sin). The other options (cotton, collaborative, cotuition) are not trigonometric terms. Cot 45° = 1 because at 45°, the adjacent and opposite sides are equal.
