    A cost (hours) = $200

    Step-by-step explanation:

    Let h represents the number of hours after which the cost of a repair is $ 200,

    Since, according to the question,

    Cost ∝ h

    We can write the cost of a repair after h hours is Cost (h)

    ⇒ Cost (h) = $ 200

    ⇒ Cost (hours) = $ 200

    Which is the required function notation for the given situation.

    Option 'A' is correct.
