The hybrid orbital of this molecule is 
. Hence, option C is correct.
<h3>What is hybridisation?</h3>
Hybridization is defined as the concept of mixing two atomic orbitals to give rise to a new type of hybridized orbitals.
In this compound, a hybrid orbital makes I-O bonds. Due to hybridization iodate should have tetrahedral geometry but because of the presence of lone pair of electrons the shape of 
the ion is pyramidal.
The hybrid orbital of this molecule is . Hence, option C is correct.

Answer:
Geosphere and hydrosphere is the correct answer to the given question .
Explanation:
The Volcanic eruption substances alter ecosystems and create pollutants and gasses in the environment as well as in the waters.The Volcanic eruption is effected the climate as well as the weather of the environment system .The volcanic eruption is simply effected the rainfall of the climate environment.
- The Geosphere and hydrosphere communicate when the amount of rain rises in the region of the following a volcanic eruption.
- All the other option are incorrect because these layer is not involved in the rising in the region of the volcanic eruption.
