A laser altimeter would be able to detect regular bulging of the icy crust on top of the ocean due to tidal forces. This would confirm the presence of a subsurface ocean. A spectrometer would not be able to detect the presence of a subsurface ocean directly, but would be able to give clues about its existence if it detected the spectral signature of liquid water beneath the surface. A camera would only be able to observe the surface of Europa and would not be able to confirm the presence of a subsurface ocean. A projectile would not be an appropriate tool as it would be destructive and could contaminate the ocean.
