उत्तर

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
