A highly elliptical orbit typically has a high eccentricity. The eccentricity of an elliptical orbit can range from 0 (a perfect circle) to just below 1 (a highly elongated ellipse). For a highly elliptical orbit, the eccentricity is typically greater than 0.8.
Among the given options, 0.9200 is the only value that indicates a highly elliptical orbit.
Therefore, the likely eccentricity of the new comet is 0.9200.
