Answer:
d. mechanical isolation
Explanation:
Mechanical isolation is a prezygotic barrier in which there is a physical barrier that prevents two populations of a species from mating successfully as a result of morphological differences.
This reproductive isolation can be seen in the Euhadra species of Japanese land snail, where snails with right hand shells and left hand shells are unable to physically corpulate successfully.
The accumulation of mineral salts in irrigated land is called soil salination. One of the undesired effects of irrigation is soil salination. Irrigation water often contains some salt at varying levels. Salt is nasty to plants and does not make themn grow, so farmers have to deal with salination by flushing the soil with extra water to leach salts out. Proper soil management and monitoring of water table is necessary to reduce impact of salination to soil quality.
The answer is B, and the same could be applied to all life as well
