Among the melting points of hydrocarbons you have given,
X hydrocarbon will have minimum carbons, because melting point is always depends on a molecular mass of molecule.
There is a proportional relation between melting points and carbon atoms.
Melting points are increases with the numbers of carbon atoms increases.
And in compare with -90°C,- 190°C is the lower temperature.
Hope it's helpful.

Still I dint understand
dear, jaise suppise if we wanna boil water, one cup of water and five cups of water
which water will boil first?
obviously one cup water will boil first.
in that way hydrocarbon which contains more carbons taking more time
to melt.
-190°C is lower temperature than 90°C
X hydrocarbon having low molecular mass thats why it melts at lower temperature -190°C than the Y hydrocarbon
Hope u got it now
Mark as brainliest if u satisfied
