Answer:
(B) Lava has separated the population into two areas: an upland forest and a lowland marsh.
Explanation:
In allopatric speciation, individuals of an ancestral species may undergo evolution into two or more progeny species which arises when physical separation causes a geographic boundary, this barrier can be in the form of a mountain range, rockslide, river or lava.
As in this scenario, a lava flow divides the populations of annual herbaceous plants by altering the landscape. This will cause genetic divergence with varying heritable features among its many generations favouring different traits in the separate environment along with genetic drift. The Lava will separates the population into two areas: an upland forest and a lowland marsh.

Na+ ion in sodium chloride is attracted to the oxygen side of the water molecules, while the Cl- ion is attracted to the hydrogens' side of the water molecule
this causes the sodium chloride to split in water, and the sodium chloride dissolves into separate Na+ and Cl- atoms
When infected by a virus, a host cell produce many thousands of identical copies of the original virus. so the answer is B
