  Eric
Correct Answer
D. Hypotenuse

Explanation
In a right-angled triangle, the longest side is called the hypotenuse. The hypotenuse is the side opposite the right angle and is always the longest side in a right-angled triangle. It is often denoted by the letter "c" in the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. Therefore, the correct answer is "Hypotenuse."

Explanation
The length of the unknown side in the given triangle can be determined by using the Pythagorean theorem. According to the theorem, in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, the unknown side is the hypotenuse. By applying the theorem, we can see that the length of the unknown side is 1.
