If 1 is adjacent to 2, 4 and 6, then which of the following statements is necessarily true?
Options
A. 2 is opposite to 6
B. 1 is adjacent to 3
C. 3 is adjacent to 5
D. 3 is opposite to 5
Correct Answer
3 is adjacent to 5
Explanation
If 1 is adjacent to 2, 4 and 6 then either 3 or 5 lies opposite to 1. So, the numbers 3 and 5 cannot lie opposite to each other. Hence, 3 is adjacent to 5 (necessarily).
