Find the word/s that can substitute the highlighted words.
The study of plant life is taught to all school children in secondary classes.

Correct option is B

The phrase "the study of plant life" specifically refers to an academic discipline focused on plants. Here's why the correct answer is (b) Botany:
· Botany is the scientific study of plants, including their physiology, structure, genetics, ecology, distribution, classification, and economic importance. It is a branch of biology that exclusively focuses on plants, making it the most precise substitution for "the study of plant life."
· Botany (वनस्पति विज्ञान) - This is the science of plant life. In Hindi, it's referred to as वनस्पति विज्ञान.
· Example: In a botany class, students might learn about how photosynthesis works, which is the process plants use to convert light energy from the sun into chemical energy.
Meanings of the other words:
· Zoology is the study of animal biology, not plants, so it doesn't fit.
· Biology is a broader field that encompasses the study of all living organisms, including both plants and animals. While it technically includes plant studies, "Botany" is a more specific and accurate term for this context.
· Sociology deals with human societies, their interactions, and the processes that preserve and change them. It has no relation to plant life.
