Sure, let's break down the types of research based on their objectives:

1. Exploratory Research: This type of research is conducted when the problem is not clearly defined. It helps in gaining insights and understanding of the problem. It is often used to generate hypotheses and identify variables that might be important for further study.

2. Explanatory Research: This type of research aims to explain the reasons behind a phenomenon. It seeks to understand the cause-and-effect relationships between variables. It is more structured than exploratory research and often involves testing hypotheses.

3. Correlational Research: This type of research examines the relationship between two or more variables. It determines whether an association exists between variables, but it does not establish causation. It helps in identifying patterns and predicting outcomes.

Given these definitions, the correct answer to the question "On the basis of objectives, the types of research are following:" is:

All of the above

This is because all the listed types (Exploratory, Explanatory, and Correlational) are indeed types of research based on their objectives.
