Explanation:

Number of students between Sohan and Mohan = 45 – ( 8 + 10 ) = 27

Clearly, there are 27 students between Sohan and Mohan. It's further given that Rohan's position is exactly between the two.

∴ Rohan's position = Total no. of students between Sohan and Mohan + 1 divide by 2

= 27 + 1 divide by 2 = 14

 Therefore the number of students between Rohan and Mohan is 13, and on counting, Rohan's position will be 14th from Mohan.

So, Rohan's position is 14th from Mohan.

Hence, option A is correct.
