    A)  18 cm            

    B)  19 cm

    C)  21 cm            

    D)  22 cm

    Correct Answer: B

     Pinnocchio's nose length = 10cm Pinnocchio?s nose length after three lies\[=10+(5\times 3)\] \[\text{=10+15=25 cm}\] Pinnocchio?s nose length after two true statements \[=25-(2\times 3)\] \[\text{25 - 6 = 19 cm}\text{.}\]
