Answer:
D. An acid accepts an electron pair from a base.
Explanation:
acorroding to lewis 
- an acid is a compound which accepts a pair of electrons from base .
 
- a base is a compound which donates a pair of electron to acid .

Explanation:
The electronegativity difference in C-C and C-H atoms is quite low. This means smaller the electron cloud. This further means larger bond length that is electron's are further from the nucleus.  hence,  higher potential energy of C-C and C-H bonds. 
On the contrary, C-O and H-O have large difference in electronegativity( O is high electronegative element) . This means smaller bond length. Electron's near the nucleus. Thus, lower potential energy of bonds.
