To arrange the given words in a meaningful sequence, we need to consider the logical order of steps involved in a typical process of getting admission to an educational institution. Let's analyze the sequence:
- Advertisement (4): Institutions first advertise the availability of courses or programs to attract prospective candidates. This is the first step where information is disseminated to the public.
- Application (2): Following the advertisement, interested candidates apply for the courses or examinations. They fill out application forms as part of the initial step towards getting admission.
- Entrance Exam (3): After applications are received, candidates typically undergo an entrance examination to evaluate their eligibility and merit for selection into the program.
- Admission (1): Finally, based on the results of the entrance exam, candidates are granted admission to the program, concluding the process.
Thus, the logical and meaningful sequence is: Advertisement (4), Application (2), Entrance Exam (3), Admission (1).
Therefore, the correct order is: 4, 2, 3, 1, which matches the given correct answer.
