Solution

The correct option is D Assertion is false, but the reason is true
In all fluids, the shear modulus is zero because if one applies a force, the liquid simply flows and the strain becomes arbitrarily large. This is why transverse waves won't propagate in fluids, because a transverse wave is a shear wave.
