    Here i is directly related to the joint of p and r, and 2 is a constant. SO in this case, correct option is joint.

    If it was i = 2p or i = 2r, then it is direct and if it was i=2/p or i=2/r, then it is inverse.

    But here it is i=2pr, that is i varies with the joint of p and r, so correct option is joint.
