B.) Red Volcanic Rock
C.) Lava Rock covered by Sulphur
Explanation:
Igneous rocks are rocks that forms from the cooling and solidification of magma. Magma is a melt or molten rock. Magma is usually derived from rocks that have been buried and subjected to extreme temperature conditions.
Red volcanic rocks and lava rocks covered with sulphur are classified as volcanic rocks. Volcanic rocks are formed from magma that settles and cools on the surface of the crust. These magma is called lava.

Answer:
(D) Increased susceptibility to plant disease- if corn is more susceptible to plant diseases, then it will be at a risk of extinction.
Explanation:
Genetic variation helps a population to develop despite varying environmental conditions as to decrease the risk of extinction. Genetic diversity is used to create improved crop varieties with traits such as yield, pest resistance and environment stress. Lack of genetic diversity in corn will make it susceptible to plant diseases and be at risk of extinction.
