Alpine tundra are high-altitude areas with tundra  landscapes.

Option: B

Explanation:

The locations where there is no growth of trees because of frozen soil or severe water runoff due to steep grades i.e at high altitudes are called tundra. High-altitude biomes have similar restrictions on plant life production. Tundra ecosystems occur where lengthy, cold winters, a covered with ice subsoil, and heavy winds blend together to discourage trees from growing. Vast regions of this biome cover the northernmost parts of North America and Eurasia, making up the tundra of the Arctic. Throughout all latitudes, weather conditions are identical throughout high mountains; these low, fragmented areas are named alpine tundra.

post-impressionism is a predominantly french art movement that developed roughly between 1886 and 1905, from the last impressionist exhibition to the birth of fauvism. post-impressionism emerged as a reaction against impressionists' concern for the naturalistic depiction of light and colour.

explanation:

metamorphism is the change of minerals or geologic texture (distinct arrangement of minerals) in pre-existing rocks (protoliths), without the protolith melting into liquid magma (a solid-state change). the change occurs primarily due to heat, pressure, and the introduction of chemically active fluids. i hoped i !
