Correct Answer: 1, 3, 4, 2

Solution : Given:
1. Examination 2. Explicit 3. Expenditure 4. Experience

Step 1: Compare the first and second letters of each word. Since all the words start with the same letters E and x , then move on to the next letter.
Step 2: The third letter of each word is either a or p . Based on the alphabetical order of these letters, we can arrange them – Ex a mination, Ex p licit, Ex p enditure, Ex p erience.
Step 3: Compare the fourth letter of (Exp l icit, Exp e nditure, Exp e rience). Expenditure and Experience will come before Explicit in the sequence as e comes before l in the alphabetical system.
Step 4: Compare the fifth letter of (Expe n diture, Expe r ience). Expenditure will come before Experience in the sequence as n comes before r in the alphabetical system.

So, the sequence is Examination, Expenditure, Experience, Explicit, or 1, 3, 4, 2. Hence, the fourth option is correct.
