Which example shows a correct match of vegetation and soil?

Correct answer: Mangroves and saline marshy soil

The direct answer is C: mangroves match saline marshy soil. A correct vegetation-soil match means that the plant’s adaptations suit the conditions of that soil and habitat. Step by step: mangroves grow along tidal coasts and estuaries; these places may be waterlogged and salty; mangroves tolerate salt and have special roots that help them live in muddy, oxygen-poor ground; therefore saline marshy soil is the suitable match. Option A is wrong because cacti are adapted mainly to dry, sandy or rocky places, not marshy soil. Option B is wrong because alpine plants need cold high mountains, not coastal saline soil. Option D is wrong because evergreen forests generally require abundant rainfall, while very low rainfall does not support them. Memory cue: mangrove means muddy, marshy and salty coast.
