The correct answer is: C. Obstructions.
An obstruction is something that blocks or hinders progress. It can be a physical object, such as a wall or a tree, or it can be an abstract concept, such as a rule or a regulation. Obstructions can make it difficult or impossible to achieve a goal.
A handicap is a physical or mental condition that limits a person’s ability to function normally. Handicaps can be caused by birth defects, accidents, or diseases. They can make it difficult or impossible for people with handicaps to participate in everyday activities.
A hindrance is something that slows down or prevents progress. Hindrances can be physical objects, such as a traffic jam or a snowstorm, or they can be abstract concepts, such as a lack of money or a lack of motivation. Hindrances can make it difficult or impossible to achieve a goal.
A promoter is someone who helps or encourages someone else to do something. Promoters can be individuals, organizations, or groups. They can provide financial support, emotional support, or practical assistance. Promoters can help people achieve their goals.
In the context of the question, the correct answer is “obstructions” because it is the only option that refers to something that blocks or hinders progress. The other options refer to things that can make it difficult or impossible to achieve a goal, but they do not specifically refer to things that block or hinder progress.
