C) It is twice Jupiter's density.
D) It is eight times Jupiter's density.

HAT P-32b's lower density compared to Jupiter's is due to its larger radius, meaning that its overall volume is larger but its mass remains about the same. Since density is calculated by dividing mass by volume, the larger volume for a similar mass results in a lower density compared to Jupiter's.
