See answer

Correct answer: (C) convex lens of fL > 10 cm
The focal length of a lens depends on the medium. Water has a higher refractive index than air, so the difference between the indices of the glass and the medium falls and the lens converges less strongly. It stays convex, but its focal length grows beyond 10 cm.
