I think it should be 30m.

30 is the correct option according to the definition.

How?

According to me, the correct answer is 30m.

The most common type of horizontal curve used to connect intersecting tangent (or straight) sections of highways or railroads are Circular curves. In most countries, two methods of defining circular curves are in use: the first, in general use in railroad work, defines the degree of curve of the central angle subtended by a chord of 100 ft (30.48 m) in length; the second, used in highway work, defines the degree of curve as the central angle subtended by an arc of 100 ft (30.48 m) in length.

The degree of curve is the central angle subtended by an arc (arc basis) or chord (chord basis) of one station. It will define the sharpness of the curve. In English system, 1 station is equal to 100 ft. In SI, 1 station is equal to 20 m. It is important to note that 100 ft is equal to 30.48 m not 20 m.
