Prefixes are the words that are added before the word. The prefix - de in the word "decongestant" means a substance that reduces congestion. Thus, option D is correct.
<h3>What is a prefix?</h3>
The complete question is: When I told the doctor of my sinus pain and nasal pressure, she offered me a decongestant. Based on the prefix, de-, what does the word "decongestant" mean?
- a device that causes congestion
- a resource that defines congestion
- a way to measure congestion
- a substance that reduces congestion
A prefix is an affix word, letter, or digit that is placed before the beginning of the stem of the original word. These when added to the words change their original meaning and are generally the opposite.
Congestion in general means the stuffy feeling in the nasal passage. The prefix de- is used as the word that means off and when used before the word congestion will mean to be off from the stuffy feeling. Hence, the word decongestant is a drug that will treat and take off the feeling of congestion.
Therefore, decongestant means a substance that reduces congestion.

They could be right underneath swimmers who would never know that they are there meaning that the swimmers could inadvertently destroy or cause damage to the habitat of the Eastern Hellbenders.
These habitats are very important to the Eastern Hellbender because as the text states, they could hide under the same rock for their entire lifespan which is on average 30 years. Those rocky bottoms are therefore very important to it's lifecycle.
