First, we need to calculate the radius of the cylinder. Since the diameter is 15.5 cm, the radius is half of that, which is 15.5 / 2 = 7.75 cm.
Next, we calculate the lateral surface area of the cylinder, which is given by the formula 2 * π * radius * height. Plugging in the values, we get: 2 * 3.14 * 7.75 * 28 = 1,739.95 cm².
Therefore, the correct answer is 1,739.95 cm².
