To compute the density of Jupiter, one obtains its mass from
A) Kepler's third law and its size from Kepler's second law.
B) its observed rotation period and its size from trigonometry.
C) Kepler's third law and its size from trigonometry.
D) its gravitational redshift and its size from Kepler's first law.
