Whether a particular exposure to a disease is related to a given outcome should involve formulating a hypothesis. The statement is true.
<h3>What is hypothesis?</h3>
A hypothesis is the first step of investigation in any field of research formulated to predict relationship between two or more variables based on evidence.
The major components includes population, variables and their relation.
The sources of hypothesis are similarity between the phenomenon, evidence from past studies, scientific theories etc.
In the field of epidemiology, researchers measure the relationship between the exposure towards disease and their outcome, define their hypothesis by asking research question and making a experimental design to solve their question.
Hence the statement is correct.

The two main types of cholesterol are the Low-Density Lipoprotein(LDL), also known as the bad cholesterol and the High-Density Lipoprotein(HDL), also known as the good cholesterol. LDL carries cholesterol to the arteries of your heart. Too much LDL may cause a formation or build-up of plaque in the arteries of the heart, blocking the passage of the blood and restricts the blood from flowing normally. This causes various heart diseases and heart problems which could lead to death. HDL on the other hand carries excess cholesterol into the liver in order to flush them away from the body’s system. High levels of HDL can help lower the risk of heart problems and/or diseases.
Answer: Option D. "Toxoid"
Explanation:
Inactivated polio vaccine (IPV) is defined as the polio vaccines which are used to prevent poliomyelitis.
IPV is produced from wild-type poliovirus strains and then they are allow to inactivated (killed) with formalin.
Toxoid vaccines is an example of IPV, which is made by inactivating the toxin that is responsible for disease symptoms and allowed an immune response against the toxin without any harm to the body. Toxoid vaccines are available for several immunizations including the tetanus and diphtheria immunizations.
Hence, the correct option is D.
