Ans is c . Here leftmost person is lying since there is nobody to his right!-

you have to visualise the rightside of the person and not yours!

Answer

The person next to rightmost person is the leftmost person so :

1. if all of them will be lying it will mean that anyone who had been accused is not guilty. Since the he did not say anything, the person next to him is guilty.

2. if the person next to him is innocent then the rightmost person will not say anthing to the next (innocent) person i.e. leftmost person

Answer

Solution:

Given, there are 10 suspects, and only one of them is guilty. Let's assume the suspects as S1, S2, S3, S4, S5, S6, S7, S8, S9, and S10.

Each person standing in the line declares that the person next to him on his right is guilty. Let's represent this information in a table as follows:

| Suspect | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 |
|---------|---|---|---|---|---|---|---|---|---|----|
| Guilty? | R | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |

Here, R represents the rightmost suspect who is not questioned. Now, let's analyze each suspect's statement:

- S1 claims that S2 is guilty, which means S1 is innocent.
- S2 claims that S3 is guilty, which means S2 is innocent.
- S3 claims that S4 is guilty, which means S3 is innocent.
- S4 claims that S5 is guilty, which means S4 is innocent.
- S5 claims that S6 is guilty, which means S5 is innocent.
- S6 claims that S7 is guilty, which means S6 is innocent.
- S7 claims that S8 is guilty, which means S7 is innocent.
- S8 claims that S9 is guilty, which means S8 is innocent.
- S9 claims that S10 is guilty, which means S9 is innocent.

From the above table and analysis, we can conclude that:

- The guilty suspect is the rightmost suspect, i.e., S10.
- All suspects except the rightmost one are innocent.
- The leftmost suspect, i.e., S1, is innocent.

Therefore, the correct answer is option C: the leftmost suspect is guilty.
