    Assertion The movements of alimentary canal, iris of the eye and bronchi of lungs are not under our will.
    Reason These are controlled by voluntary muscles.

    A) Both A and R are true and R is correct explanation of the A

    B) Both A and R are true, but R is not the correct explanation of the A

    C) A is true, but R is false

    D) A is false, but R is true

    Correct Answer: C

    Solution :

    [c] Assertion is true, but Reason is false.
    Voluntary muscles are the muscles, which are under our complete control, e.g. the working and movement of limbs.
    On the other hand, involuntary muscles are controlled by hypothalamus, i.e. they are regulated rhythmically; e.g. alimentary canal, iris of the eye and bronchi of lungs.
