Answer:
B. Iron nails are attracted to the magnet
Step-by-step explanation:
A qualitative observation is an observation that gives qualitative data -as opposed to quantitative-. This means that the data is non-numerical (or unquantifiable). In other words it could be said that a qualitative observation can be reached when you don't count anything. In chemistry qualitative observations can be made of properties such as color, smell, or whether or not a species is attracted to a magnet.
