The correct answer is option 1: temperature is highest and pressure is the lowest in the innermost region of a hurricane, known as the eye.

Option 1 explains that the temperature is highest in the eye of a hurricane. This is because the eye is a region of relatively calm and clear weather, where sinking air warms and dissipates the clouds. The absence of clouds allows the sun`s radiation to directly heat the surface of the ocean, which in turn warms the surrounding air.

Option 1 also mentions that the pressure is the lowest in the eye of a hurricane. This is because the eye is a region of descending air, which creates higher air pressure at the surface. The low pressure in the eye is surrounded by the higher pressure in the surrounding eyewall, where the most intense winds and precipitation occur.

Overall, option 1 correctly describes the characteristics of the innermost region of a hurricane, known as the eye.
