Explanation:
A fault is a product of brittle deformation in which a displacement occurs within the earth.
A normal and reverse fault both have an hanging wall and a foot wall.
- In a normal fault, the footwall moves upward and the hanging wall moves downward thereby causing extension.
- In a reverse fault, the footwall moves downward and the hanging wall moves upward thereby causing shortening.
- The footwall is the block on a side of the fault surface where a miner can stand whereas the hanging wall is the block on the other side.

The correct answer is - C. Colombia.
Colombia has a long tradition in coca production and than illegal trade with cocaine and unfortunately this is what is the country's trademark. Unlike some of the South American countries where it is noticed a drop in coca production, Colombia is actually having an increase in production, and a very significant one, every year in the past 6 years there's more and more plantations with coca and there is more and more cocaine production that ends up illegally all over the world. This process is mainly sponsored and under the wings of the Colombian cartels.
