Which carbon is more electronegative ?

Assertion : CH_(3)C equiv CH is more polar than CH_(3)CH = CH_(2) . Reason : sp-carbon is more electronegative than sp^(2) carbon.

Assertion: sp^(3) hybrid carbon atom is more electronegative than sp hybrid carbon atom. Reason: sp^(3) hybrid orbitals are more closer to the nucleus.

In which of the following carbon is most electronegative?

Assertion(A): CH_(3)C-=CH is more than CH_(3)CH=CH_(2) Reason:sp-carbon is more electronegative than sp^(2) carbon
