I believe the correct answer is involuntary
<h2>Explanation</h2>
The human body has 2 groups of muscles; voluntary and involuntary that are divided into 3 types of muscles: Cardiac muscles found only in the heart, smooth muscles found in hollow organs and also internal organs and skeletal muscles that support the human skeleton and also protect organs. An example is the thigh muscle. Of the muscles, Cardiac muscles and smooth muscles are completely involuntary in addition to diaphragm which is a skeletal muscle.
<h2>Further Explanation</h2><h3>1. Cardiac Muscle</h3>
The cardiac muscle is found only in the heart and is controlled by the brain only. It is the reason why your heart beats without your control. The part of the brain responsible for this control is a region called pons in the hind brain. It is an involuntary muscle. It also is different in structure to all the other types of muscles.
<h3>2. Smooth muscles</h3>
These are muscles found in organs and also lining of some organs such as blood vessels and the bronchioles. They also form organs such as the liver, lungs and uterus. They are involuntary muscles that are under the control of the brain and perform functions such as breathing and regulation of body temperature and blood pressure.
<h3>3. Skeletal muscles</h3>
This is the most common type of muscle and is found in almost everywhere you touch for example the thighs, arms, legs, head, chest. They are tough muscles that coordinate to help the skeleton in movement, protect internal organs and also link up body parts. You can control them and they are voluntary. For example, when you stand up you use your skeletal muscles.

The closes answers are B and C.
But the best is B. <span>Fermentation is a process that uses substances such as bacteria or yeast to change the sugars of fruits or grains into alcohol.
</span>
Fermentation is simply the conversion of sugars into alcohol using microorganisms.
Option A refers to fermentation as a rate (how quickly) which is inaccurate. Option C is somewhat accurate because it only mentions about bacteria and it includes the process of extracting sugar. Option D does not talk about any transformation from sugar to alcohol.
False.
