The correct answer is: B. Objectives of the research.
The objectives of a research are the specific goals that the researcher hopes to achieve. They are the foundation of the research and determine the methods that will be used. The depth of a research can be judged by the extent to which the objectives are met. If the objectives are ambitious and well-defined, then the research is likely to be deep. If the objectives are vague or not well-defined, then the research is likely to be shallow.
The title of a research is simply a name that is given to the research. It does not provide any information about the depth of the research. The total expenditure on a research is also not a good indicator of its depth. A research can be expensive without being deep, and a research can be inexpensive without being shallow. The duration of a research is also not a good indicator of its depth. A research can be long without being deep, and a research can be short without being shallow.
In conclusion, the depth of a research can be judged by the objectives of the research. If the objectives are ambitious and well-defined, then the research is likely to be deep. If the objectives are vague or not well-defined, then the research is likely to be shallow.
