Assertion and Reason both are correct but Reason is not the correct explanation of Assertion.

Vedclass · Answer

(B) Assertion is true because compact bone tissue contains structural units called osteons or Haversian systems,which feature central Haversian canals.Reason is also true because Volkmann's canals (perforating canals) run transversely and connect Haversian canals to each other and to the periosteum.While both statements are factually correct,the presence of Volkmann's canals is a structural feature of bone,but it does not explain why human bone possesses Haversian canals in the first place. Therefore,the Reason is not the correct explanation of the Assertion.

$A$ : Human bone has Haversian canals.
$R$ : Haversian canals are interconnected by Volkmann's canals.
