Explanation:
B. The lower the concentration of hydrogen ions, the higher the acidity is.
C. The greater the concentration of hydroxide ions, the higher the acidity is.
D. The greater the pH is, the lower the acidity is.
The pH scale measures the acidity or basicity of a solution. The higher the pH, the lower the acidity and the lower the pH, the higher the acidity. It is based on hydrogen ion concentration.
The pH scale is a logarithmic scale used to specify the acidity or basicity of an aqueous solution. It ranges from 0 to 14. A solution with a pH less than 7 is acidic, one with a pH of 7 is neutral, and one with a pH greater than 7 is basic. Therefore, option D is the correct answer. The greater the pH is, the lower the acidity is. The lower the pH, the higher the acidity, and vice versa. This scale is based on the concentration of hydrogen ions (H+) and hydroxide ions (OH-).

b.stormy
c.hot
d.tranquil
Option (D) Tranquil best describes the eye of the hurricane.
In the heart of tropical cyclones, there is typically calm weather.
They are between 20 and 50 kilometers in diameter and are located at the center. The hurricane's eye is its focal point, the point around which the remainder of the storm revolves, and where its lowest surface pressures are located.
Above the eye, skies are frequently clear, and winds are generally mild.
The eye is so tranquil because it is never reached by the now powerful surface winds that are converging towards the center. The coriolis effect causes the wind to revolve around the hurricane's core (the eye wall), slightly deflecting it away from the exact center (the eye), which remains calm.
Therefore, option (D) best describes it.
