C.Drug target-interaction
D.Photography

Answer 1

Hint: Use of chemicals can be done in different ways for different purposes giving rise to various fields that are named accordingly.

Step by step answer: All of us use many chemicals in our daily lives from those used in food; from fertilizers, pesticides to preservatives; in cleansing agents as soap and detergents or as fuel in kitchen, vehicles, satellites and so on. Here, we will talk about their use in medicinal areas.

As we can see that chemicals interact with other chemicals or their surroundings and we observe some effects such as cleaning effect of soaps, heating effect of fuels. Similarly, when chemicals interact with some macromolecular target in living organisms, we observe a biological response and these chemicals are called drugs. Now, the biological response can be useful or harmful based on various factors.
When the biological response is therapeutic, the chemicals are called medicines and their use is known as chemotherapy.

When we use a drug, it interacts with a macromolecule target such as enzymes, receptors, lipids or carbohydrates. All these molecules perform specific functions in our body and it is their malfunctioning that might result in some disease as well. So, we can use drugs that would interact with a specific target to result in a desirable effect. This is known as drug-target interaction.

Hence, we can say that the correct option is B.

Note: At present, chemotherapy is mostly related and heard in case of cancer treatment but in general it is use of chemical for any therapeutic effect
