Navigational tolerance for RNP is expressed as which?

Explanation:
RNP defines how precisely you must stay on the intended path. The navigational tolerance is the lateral deviation allowed from the centerline, described as a radius around the path equal to the RNP value. So the tolerance is stated as plus or minus the RNP value. For example, with RNP 0.3 NM, you must remain within 0.3 nautical miles on either side of the course. This expresses the tolerance directly in terms of the RNP parameter rather than as an angle or as a single fixed distance. The other options using degrees or a fixed distance don’t capture how RNP conveys the allowable lateral deviation; the key concept is that the tolerance is ± the RNP value.
