      Either

    • D.

      None

    Correct Answer
    B. 1/2 of buccolingual width
    Explanation
    The occlusal rest should ideally measure 1/2 of the buccolingual width. This means that the occlusal rest should be approximately half the width of the tooth from the buccal (cheek) to the lingual (tongue) side. This measurement is important for providing proper support and stability for a dental prosthesis or restoration. By having a rest that is half the buccolingual width, it ensures that there is enough surface area for the restoration to securely fit and distribute forces evenly during occlusion.
