A mission that NASA is planning to launch between 2022 and 2025 will be able to confirm the presence of a subsurface ocean on Europa by using a

A) spectrometer to detect the spectral signature of liquid water at and beneath the surface
B) camera to observe the formation and breakup of icebergs on the surface
C) projectile to break the thin icy crust to reveal the water below
D) laser altimeter to detect the regular bulging of the thin icy crust on top of the ocean due to tidal forces
