Answer & Explanation
C) If the data either in I or II alone are sufficient to answer the question;
Comparing the information in the question with statement 1. we find that '2' and '9' are the codes for 'tie' and 'dip'. So, '7' represents 'button'.
Thus, I alone iS sufficient.
Again, comparing the information in the question with II, WO find that the common code number '7' stands for the common word 'button'.
Thus, II alone also is sufficient.
