In accordance with the Bernoulli principle, as the water get In the narrow region, its gains speed and the bubbles are <u>larger</u>.
<h3>What is the Bernoulli's principle?</h3>
The concept explains that an increase in a liquid's speed creates a pressure decrease and decrease in a liquid's speed creates a pressure increase.
Hence, as the water get In the narrow region, its gains speed and the bubbles are becoming larger because of the pressure.
Therefore, the Option C is correct.
