| Assertion : Regeneration blastema is a bud-like structure formed during regeneration of limb in salamander. |
| Reason : Formation of regeneration blastema involves dedifferentiation. |
A) If both the assertion and the reason are true and the reason is a correct explanation of the assertion
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
