qstn 1: sawfish skeleton is made of cartilage is given in both option and description.. but why wrong???

Both shark and saw fish skeletons are made of cartilage (option : 2 , mentioned unlike sharks )
sir a condition is given that ∆Q/T =0 and ∆S greater than 0 and in options​ it is given that is it reversible adiabatic or irreversible adiabatic
it's a contradictory Question.... is there any other options?
see if ∆S(system or surrounding)>0 and ∆Q/T=0 then it may or may not be reversible.... if Q is zero then it is a adiabatic process.... if ∆s(universe)>0 then it is irreversible...
Why we treated vfg as volume

  3. The vapour pressure of liquid ammonia (in atmosphere) in the vicinity of the triple point can be expressed as 3063-15.16 where temperature T is expressed in K In a similar manner, the vapour pressure of solid ammonia can be expressed as In p +--=18.7 Take the molecular mass of ammonia to be 17 kg/kmol Q.1 The temperature and pressure at the triple point are (B) 295.2 K, 0.59 atm (D) 195.2 K, 0.59 atm (A) 295.2 K, 0.69 atm (C) 195.2 K, 0.69 atm The latent heat of vapourization is (A) 1298 kJ/kg Q.2 (B) 1398 kJ/kg (C) 1498 kJ/kg (D) 1698 kJ/kg
