Which one of the following statements best explains the greater acidity of terminal alkyne...

Which one of the following statements best explains the greater acidity of terminal alkynes (RC≡CH) compared with monosubstituted alkenes (RCH=CH2)?

A) The sp -hybridized carbons of the alkyne are less electronegative than the sp2 carbons of the alkene.

B) The two π bonds of the alkyne are better able to stabilize the negative charge of the anion by resonance.

C) The sp -hybridized carbons of the alkyne are more electronegative than the sp2 carbons of the alkene.

D) The question is incorrect - alkenes are more acidic than alkynes.
