Option 1 states that both statements are true and that Statement II is the correct explanation of Statement I.
Statement I states that there is high salinity in the Red Sea. This means that the water in the Red Sea has a high concentration of salt.
Statement II states that the rate of evaporation is high in the Red Sea. This means that water in the Red Sea has a higher tendency to convert from a liquid state to a gas state due to the high temperature and low humidity in the region.
The explanation given in Statement II supports the high salinity in the Red Sea. When water evaporates, it leaves behind the dissolved salts, causing the remaining water to become more saline.
Therefore, Option 1 is correct because both statements are true and Statement II provides a logical explanation for the high salinity in the Red Sea.
