B) If both the assertion and reason are true but the reason is not a correct explanation of the assertion
C) If the assertion is true but the reason is false
D) If both the assertion and reason are false
E) If the assertion is false but reason is true
Correct Answer: B
Solution :

The lower surface is correspondingly called outer, abaxial or dorsal surface. A distinction with upper and lower surfaces is absent in isobilateral surface.
