The correct answer is Option b) Sinking Land

Mexico City is the capital of Mexico and is one of the biggest centers in the world in terms of population. Despite being the capital and the commercial center of the country, it is suffering a huge difficulty of the sinking of the land.

In the past 60 years, the town has fallen several feet because it was formed on top of smooth land with a large aquifer below it.

As the population of the capital is growing, the aquifer has decreasing in size. Today, in some severe instances, some parts of the capital are sinking by  1 foot every year. In the last century alone, Mexico City has declined nearly 30 feet.
