C. They would crystallize at high temperature because they are mafic.
Explanation:
According to the Bowen's reaction series, the rocks with a high magnesium and iron content would crystallize at high temperature because they are mafic.
Mafic rocks are usually formed at high temperature and they are rich in ferromagnesian minerals such as olivine and pyroxene.
- They are shown towards the top part of the discontinuous end.
- Mafic rocks are usually formed at high temperature.
- They have a high amount of magnesium and iron in them.
- These element allows for a rock rich in mafic minerals to form.
- Such minerals forms mafic rocks like pyroxenite, basalt etc.
- At the lower end are the felsic.
- They are rich in silica and are predominantly made up of feldspars and silica.

Dams are important because:
They provide water for domestic, industry and irrigation purposes.
Dams often also provide hydroelectric power production and river navigation.
Domestic use includes everyday activities such as water for drinking, cooking, bathing, washing, and lawn and garden watering.
Dams and their reservoirs provide recreation areas for fishing and boating.
They help people by reducing or preventing floods. During times of excess water flow, dams store water in the reservoir; then they release water during times of low flow.
