    A. 3h+17

    Step-by-step explanation:

    Given,

    The initial number of unloaded trucks = 17,

    Also, 3 trucks per hour can be uploaded,

    So, the additional number of uploaded truck after h hours = 3h,

    Hence, the total number of uploaded trucks after h hours = Initial uploaded trucks + additional trucks

    = 17 + 3h

    Which is the required equation,

    Option A is correct.
