Answer:
C) Question marks
Explanation:
Pharmaceutical units, shown in the above question, best fit the category called "question marks". This category includes products that are at the beginning of their life cycle, that is, that have a small and recent market share. Because they do not yet have a clear prediction of their performance, they usually require a large marketing investment to promote sales and therefore do not result in many initial profits.
The term question mark has been adopted to indicate that there is doubt about the product's yield and the feasibility of investing in its development. Care must be taken with the amount of question mark products as they require large investments.

Photosynthesis is measured by the amount of oxygen produced. Counting pondweed bubbles or using the Audus apparatus to determine the amount of gas evolved over time can both be used to quantify oxygen.
<h3>
What is photosynthesis?</h3>
Photosynthesis is the conversion of light energy into chemical energy by green plants and other organisms. Light energy is collected and utilised by green plants during photosynthesis to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic molecules.
The forming bubbles are either counted or recorded using light barriers, which is difficult due to their small size and frequently changing ascent velocity. When gas bubbles produced during photosynthesis by aquatic plants leave the plants, they produce different sound pulses.
B. Because the gas collected contains water vapor in addition to oxygen, it is not pure oxygen.
