A metric ruler measure a legth not a volume.
ml
Not neccessarily, but it rarely isn't these days.
The property is volume, more specifically of a liquid, which can be measured using a graduated cylinder.
A graduated cylinder, and a millilitre.
Graduated cylinder
a metric measuring cup
in the metric system the lines refer to milliliters
If the object is oddly or irregularly shaped, then it's much easier to measureits volume with the graduated cylinder than with the ruler. But the volumeis the same no matter how it's measured. If the results are not the same,then at least one and possibly both measurements were done wrong.
The question I see asks to choose between A. microscope; B. metric ruler; C. funnel; D. graduated cylinder. B. Metric ruler seems to be the obvious choice
A graduated cylinder is a piece of laboratory glassware, cylindrical in shape and graduated, used to accurately measure out volumes of liquid reagents for use in reactions.Related Information:They are generally more accurate and precise for this purpose than beakers or Erlenmeyer flasks, although not as precise as a volumetric flask or volumetric pipette. They come in a variety of sizes for different volumes, typically 10 ml, 25 ml, 50 ml, or 100 ml, 500ml, and up to 2 liters. Measuring cylinders are sometimes used, if they can measure the quantity desired.Determine the volume contained in a graduated cylinder by comparing the bottom of the meniscus (the curved surface of the liquid) to the nearest graduation, at eye level.

No - the metric system uses ml - millilitres for small volumes
