    The correct answer is (b) 25 ml.

    Petri plates are commonly used in microbiology to grow and culture microorganisms. The plates are typically made of plastic or glass and consist of a shallow dish with a loose-fitting lid. The lid helps to prevent contamination while still allowing for air exchange.

    The growth medium used in petri plates provides the necessary nutrients for microorganisms to grow and reproduce. The amount of growth medium that can be added to a petri plate is limited by the size of the plate and the depth of the dish.

    Standard size petri plates have a diameter of \approx imately 90 mm and can typically hold up to 25 ml of growth medium. This volume allows for a thin layer of growth medium to be spread evenly across the dish, providing a suitable environment for the growth of microorganisms.

    Therefore, the correct answer is (b) 25 ml.
