- the bulk modulus is infinite.
- the bulk modulus is zero.
- the shear modulus is infinite.
- the shear modulus is zero.

Solution
a and d
Explanation:
Because as an ideal liquid is not compressible
Bulk modulus
`(K) = (-p(V))/(ΔV)` .......(∵ ΔV = 0)
As ΔV = 0 for ideal liquid
Therefore, K = ∞ for the ideal liquid
Since, no tangential force on the liquid, shearing strain
Δθ = 0, F = 0
`H = (F/A)/(Δθ) = 0/0` = indeterminate value
