The right option is B. The color of flowers is compared.

Qualitative observation is a type of observation that deals with data or information that can be observed with the senses such as sight, taste, touch, and smell. Qualitative observation does not make use of measurements such as height or numbers, but it describes the appearance of an object using descriptive language. Qualitative observations include colors, shapes, and textures of objects.


The color of the flowers is considered a qualitative observation.

Further Explanation:

The people observe things in plenty of ways. Some use numbers in their observations while others use their senses while observing. The later ones are called qualitative observations.

Qualitative observation accounts for the data which is observed through our senses such as smell, taste, touch, sight, and hearing. These observations do not include numbers or measurements. For example shape, color, and texture of materials display qualitative observations.

While observing things qualitatively, one can just see and determine the color and shape of leaves or flowers or fruits which does not include numbers in any way. This is done by the sense of sight. The qualitative observations are not accurate, not measurable, and are not recorded as numbers.

On the other hand, quantitative observations are invariable, measurable, accurate, and can be recorded as numbers. The instrument used while recording the observations are balances, rulers, beakers, and thermometers.

Here, the color of the flowers can be observed through naked eyes which then can be compared. The color observation is not measured in numbers or through any measurable device. It can simply be observed through sight. Therefore, it is a qualitative observation.

The height of the radish seedlings, weight of three weeks old chicken, and volume of carbon dioxide gas are all determined through measurable instruments. The observed height, weight, and volume are measured and written in numbers. As a result, these observations are considered as quantitative observations.
