Final answer:
When 'ONJ' is changed to 'AROJ', the term that is obtained is 'AROJ', making option 2 the correct answer.
Step-by-step explanation:
The term that is obtained when ONJ is changed to AROJ is AROJ. This type of question typically falls under pattern recognition or spelling, which are often found in English or language arts assessments. The student is asked to find out what term results from substituting some letters in the original sequence with new ones. In this case, 'N' is replaced with 'R', and the sequence is kept in the same order, so the correct term after the change is 'AROJ', which corresponds to option 2).
