The most likely observation the scientist would make is: The plant withers and dies.

Blocking the stomata with petroleum jelly prevents the plant from conducting gas exchange, which is crucial for processes like photosynthesis and respiration. Without the ability to take in carbon dioxide and release oxygen, as well as losing the ability to regulate moisture, the plant is likely to suffer from stress, leading to wilting and eventual death.

In the photosynthesis reaction, the typical balanced equation is represented as:

\[ 6 \text{CO}_2 + 6 \text{H}_2\text{O} \rightarrow \text{C}6\text{H}{12}\text{O}_6 + 6 \text{O}_2 \]

This indicates that 6 molecules of carbon dioxide (CO₂) are required, which means 6 carbon atoms combine in the overall photosynthesis reaction.

So, the correct response is: 6.
